The work addresses one of the central challenges in microrobotics: how to create compact actuators capable of producing useful motion without relying on bulky motors, gears, wires, or conventional batteries. Microrobots designed for medicine, industrial inspection, environmental monitoring, and microassembly must operate in confined spaces, while soft robots need components that can bend and deform without breaking. Traditional ceramic materials are attractive because they can withstand heat, chemicals, and mechanical wear, but they are normally brittle. The Stuttgart-led team overcame this limitation by engineering ceramic films with a hierarchical structure that allows them to flex elastically while retaining the functional properties of the material.

The design was inspired by the proboscis of a butterfly, although the researchers did not attempt to reproduce its biological function. Instead, they focused on the proboscis’s ability to coil and uncoil smoothly. That motion suggested a route toward an actuator in which a flat film could be transformed into a tightly wound scroll and then deployed on demand. The researchers used ultrathin vanadium pentoxide films containing magnetic iron oxide nanoparticles. Vanadium pentoxide was selected because of its established role in the team’s materials research, while the embedded magnetic particles provided a mechanism for controlling the structure remotely.

The manufacturing process is deliberately simple. The functional film is first prepared as an ultrathin layer on a supporting substrate. A razor blade is then used to gently peel the film away. As the blade advances, the released portion bends continuously and curls around itself, much like a thin sheet being rolled by a miniature woodworking plane. In a matter of seconds, the flat material becomes a compact microscroll. This mechanically assisted process avoids the need for complex three-dimensional fabrication and could potentially be adapted to a wide range of thin-film materials. The researchers describe the scrolling step as a platform rather than merely a method for producing one particular actuator.

Once formed, the microscroll responds to an external magnetic field. When a magnet is brought close, magnetic nanoparticles embedded throughout the ceramic structure experience a magnetic force and torque. Their collective response pulls the scroll open, rapidly unrolling the ceramic film. When the magnet is removed, the microscroll returns to its coiled configuration. The movement results from the interaction between the magnetic particles and the elastic energy stored in the rolled film. In this sense, the device behaves like a microscopic spring whose position can be controlled without physical contact. Because the actuation is wireless and does not require an onboard power source, it could be especially valuable in environments where conventional electrical connections are impractical.

The unusual performance of the microscrolls comes from their internal architecture. Electron microscope images show multiple structural levels, from the ceramic film itself to nanoscale and microscale features distributed throughout it. This bio-inspired hierarchical organization helps prevent the brittle fracture normally associated with ceramic materials. Instead of concentrating stress at a single point, the layered structure can distribute mechanical loads across the film as it bends and rolls. The result is a material that combines the durability and functional stability of a ceramic with the flexibility normally associated with polymers or thin metallic foils. That combination is difficult to achieve and is central to the device’s ability to survive repeated deformation.

In experiments, the microscrolls demonstrated a combination of size, strength, speed, and durability that could make them useful as actuators for future robotic systems. Coiled scrolls measured only a few hundred micrometers in diameter, while their extended length could reach 25 millimeters. Their ability to move loads exceeding 30 times their own weight indicates that the structures can generate significant force relative to their mass. They also remained functional after 5,000 actuation cycles, an important result for robotic components that must operate repeatedly rather than perform a single movement. The researchers say the microscrolls can be organized into programmable arrays, allowing several actuators to move together and lift, transport, or manipulate microscopic objects in coordinated ways.

Such arrays could give microrobots a new form of mechanical intelligence. Individual scrolls could serve as grippers, hinges, locomotion elements, valves, or deployable structures, while groups of scrolls could produce synchronized movements. In a medical setting, remotely controlled microscale actuators might eventually contribute to tools designed to navigate narrow biological spaces, although substantial development and testing would be required before any clinical application. In industrial environments, the same principle could support miniature manipulators for assembling delicate components or handling particles too small for conventional machines. Soft robots could also benefit because the ceramic scrolls provide controlled movement while remaining compact and mechanically resilient.

The researchers emphasize that the broader significance of the work lies in the scrolling platform itself. The same mechanically assisted process may be transferable to other organic and inorganic thin films, including materials designed for sensing, energy storage, electronics, or multifunctional devices. By combining chemical composition, magnetic functionality, internal architecture, and mechanical processing, the platform could produce small systems that change shape in response to external signals. The work grew from a DFG-funded project, with early experiments conducted by Semi Kim during a master’s thesis in 2023 and later expanded by the research team. For the scientists, the butterfly-inspired microscroll is therefore not an endpoint but a demonstration of how biological motion can guide the engineering of programmable materials for the next generation of miniature machines.

Traditional magnetic actuators have long relied on embedding rigid magnets onto the surface of soft robotic systems, an approach that invariably compromises the surface area and the robot’s overall flexibility. Contrastingly, the novel method developed by lead author Xiaomeng Fang and her team leverages a thin magnetic elastomer film directly printed onto the critical segments of origami robots. By dramatically reducing the bulk introduced by conventional magnets, this paradigm allows the robots to retain their essential folding dynamics without hindrance, essentially acting as artificial muscles that breathe life into meticulously folded paper-like structures.

Central to this innovation is the adaptation of the Miura-Ori origami fold, a pattern renowned for its remarkable ability to transform large flat sheets into compact forms without destroying the geometry. By applying the soft magnetic films to specific facets of these Miura-Ori patterns, the researchers created robots capable of controlled expansion and contraction when subjected to external magnetic fields. Crucially, the “magnetic muscles” do not act as passive joints but actively impart force, facilitating complex motions reminiscent of biological systems and enabling robots to adaptively interact with their environment.

One of the flagship prototypes is a medically oriented soft robot engineered to deliver medication non-invasively to ulcers within the human gastrointestinal tract. Mimicking a miniaturized origami capsule, this device, upon ingestion, remains folded for passage through the digestive system. Upon reaching the targeted location, external magnetic guidance triggers the magnetic muscles to unfold the structure, securing the robot in place for controlled drug release. This approach circumvents the invasiveness of conventional endoscopic procedures, allowing patients to continue daily routines without disruption, marking a significant milestone in personalized medicine.

The fabrication process of these magnetic films posed substantial challenges due to the dual need for flexibility and magnetic responsiveness. Conventional exposures of polymeric magnetoactive inks to ultraviolet light proved insufficient for curing when these inks contained high concentrations of ferromagnetic particles. The pigmentation and density of the ferromagnetic inclusions attenuated UV penetration, impairing the crosslinking process essential for solidifying the elastomer matrix. Addressing this, the research team ingeniously combined UV curing with a thermally heated collecting platform, ensuring rapid and thorough curing even in densely loaded magnetic composites, a crucial breakthrough enabling up to 75 weight percent particle loading.

High loading of ferromagnetic particles correlates directly with enhanced magnetic force generation, a key factor in achieving potent actuation. The synergy between the dual curing mechanism and material composition facilitated the creation of films that maintained flexibility while delivering powerful, programmable magnetic responses. These films can be precisely patterned during printing, granting the ability to tailor the magnetic polarity and distribution to optimize actuation mechanics depending on the robot’s intended function and environment.

Beyond the realm of drug delivery, the researchers designed a second origami robot exhibiting crawling locomotion, reminiscent of biological organisms such as inchworms. Equipped with strategically placed magnetic muscles, this crawler contracts and expands in response to alternating magnetic fields, stepping forward incrementally. Notably, it demonstrated the ability to traverse obstacles up to 7 millimeters high and adapt to uneven terrain, including granular substrates like sand. The speed and gait modulation are finely tunable through magnetic field strength and frequency adjustments, showcasing an elegant model of soft robotic mobility.

The integration of soft magnetoactive materials and origami architectures opens fertile ground for multifaceted applications. From biomedicine to space exploration, these lightweight, wireless, and scalable actuators offer unparalleled adaptability. Aerial drones, space deployable antennas, and other complex systems prone to environmental constraints or requiring compact stowage might benefit from these innovations. The modularity inherent in origami designs complements the dynamic nature of soft actuators, potentially ushering in a new era of robotics where form and function co-evolve seamlessly.

Furthermore, the study paves the way for robots that are not only physically compliant but also possess programmable mechanical intelligence by harnessing magnetic fields. Unlike pneumatic or cable-driven actuators, these magnetic muscles afford rapid response times and wireless control without the encumbrance of bulky power supplies or tethered connections. This enables the development of minimally invasive devices operating in constrained or inaccessible environments, including inside living organisms.

The researchers verified the drug delivery robot’s performance using a mock stomach model—a plastic sphere filled with warm water, simulating human physiological conditions. By maneuvering the robot magnetically to a designated ulcer site and then actuating its unfolding mechanism, they demonstrated precise navigation and retention capabilities. The robot’s secure fixation via supplementary soft magnetic films enhances drug delivery stability, ensuring sustained, controlled release, a vital attribute for therapeutic efficacy and patient safety.

Soft robotics is a swiftly advancing field characterized by the pursuit of materials and designs that inherently coexist with delicate biological tissues and complex environments. This research embodies that spirit by marrying the ancient art of origami with cutting-edge magnetoactive materials and advanced 3D printing technologies. The result is a platform that is not only asynchronous with traditional rigid robotics but also heralds transformative approaches to actuation, control, and application.

The team emphasizes the untapped potential still residing in origami-inspired structures combined with soft magnetic films. The variation in fold patterns, actuator placement, and programmable magnetic directions is vast, suggesting a rich landscape for future innovations. Efforts to scale the technology for larger or smaller constructs, introduce sensing capabilities, and explore alternative magnetic materials and composites are logical next steps. These directions could fuel a new wave of responsive robots that autonomously adapt to complex tasks ranging from surgical assistance to exploration missions on extraterrestrial terrains.

In sum, this study illustrates an elegant marriage of materials science, mechanical engineering, and robotics, leveraging the unique properties of 3D-printed soft magnetoactive films and origami structures to forge versatile soft actuators. The promising prototypes—a drug delivery system and a terrain-adaptive crawler—signal the vast horizons for such technology. As external magnetic control permits wireless direction and power, these robots epitomize a new class of multifunctional, scalable, and embedded actuation systems poised to fundamentally alter how we imagine robotic movement and interaction in constrained spaces.

In recent years, the use of soft robotics in rehabilitation has gained traction. These systems can adapt to the individual needs of patients, offering personalized therapy solutions that can evolve as the patient’s condition improves. The adaptive nature of soft robots ensures that they remain effective over time, allowing for a continuous feedback loop where the device aligns itself with the user’s recovery progress. This stands in stark contrast to conventional rehabilitation tools that offer a one-size-fits-all approach, often resulting in suboptimal results.

One of the standout features of soft robotic actuators is their ability to modulate stiffness. This property is essential in applications where varying support is needed, such as during different phases of rehabilitation or in assistive devices for activities of daily living. The capacity to dynamically adjust stiffness allows these devices to provide rigid support when necessary, while also transitioning to a softer, more compliant state when gentleness is required. This capability simulates the natural biomechanics of the human body, leading to a more intuitive interaction and lesser injury risks for the user.

Further research into soft actuators indicates the potential for integrating advanced sensing capabilities into these robots. By embedding sensors within the soft structure, these devices can not only respond to external stimuli but can also monitor physiological parameters in real-time. Such feedback can enhance the efficacy of rehabilitation strategies, allowing clinicians to make data-driven decisions that tailor the therapeutic experience to each patient. For instance, a wearable soft robotic exosuit could adjust its assistance level based on the wearer’s heart rate or muscular response, ensuring optimal support throughout their activities.

The pursuit of sustainable practices in soft robotics is becoming increasingly vital as we move toward a future where environmental concerns are front and center in technology development. Researchers are actively exploring self-healing materials that can recover from damage, thus extending the lifespan of robotic devices and reducing waste associated with frequently replacing broken or outdated equipment. This not only promises to lower costs for users but also contributes to a more sustainable ecosystem for wearable technologies.

Another area ripe for exploration is self-powering mechanisms in soft robotic systems. Traditional wearables often depend on external power sources, which can restrict mobility and introduce downtime for recharging. Advances in energy harvesting techniques—such as those utilizing body heat, kinetic movement, or solar energy—could lead to the development of soft robotic devices that generate their own energy. This innovation would heighten user convenience and help establish a new standard for minimalistic, yet highly functional, wearable technology.

The concept of self-actuation in soft robotics also presents intriguing possibilities. Imagine a soft wearable that can autonomously adapt its form and function in response to complex environmental demands. By integrating intelligent control systems that incorporate machine learning algorithms, these devices could analyze and adapt to the user’s movements and intentions in real time. Such technology could fundamentally change the landscape of assistive devices, making them not just tools, but responsive partners in daily activities and rehabilitation processes.

Moreover, the intersection of machine learning and soft robotics could foster unprecedented advancements in personalization and adaptability. Utilizing vast amounts of data collected from user interactions, machine learning algorithms can identify patterns and predict user needs, allowing devices to optimize their performance accordingly. Such a feedback-rich environment empowers users, giving them tailored experiences that adapt over time, increasing both efficacy and satisfaction in rehabilitation and assistance scenarios.

However, the journey toward widespread adoption of soft robotics in wearable applications is not without challenges. Developers face numerous hurdles related to the integration of materials capable of withstanding daily wear and tear while maintaining functionality. Issues surrounding biocompatibility, durability, and comfort must be addressed to facilitate user acceptance.

By mimicking these efficient and reversible adhesion strategies presented in nature, the team has perfected innovative methodologies that can employ chemical bonding, negative pressure, suction, and even capillary forces for underwater interactions.

The significant advancement detailed in their recent work is the creation of starfish-like tube feet, designed to achieve temporary and switchable adhesion that responds dynamically to varying stimuli. The starfish, notable for its unique tube feet that demonstrate remarkable adhesion capabilities, inspired the design of these new robotic appendages. Professor Yoon and his collaborators have structured the artificial tube feet by integrating two cylindrical components with differing mechanical properties—a soft hydrogel for the foot and a more rigid stem to support its actions.

During operation, the hydrogel component plays a crucial role. As it absorbs water, the hydrogel undergoes swelling, allowing it to morph into a soft, cupped pad perfectly suited for adhesion. This shape modification facilitates broader contact with the targeted surfaces, crucial for achieving the desired adhesion. It’s a strategic design that not only mimics nature but also optimizes functionality, resulting in a remarkable adhesion force that can reach as high as 65 kPa. Such force can enable underwater robots to engage with previously inaccessible environments, offering unprecedented utility.

Furthermore, the artificial tube feet exhibit impressive adhesion hysteresis, supporting automatic detachment triggered by external stimuli, further enhancing their versatility. The engineering team has demonstrated the practical capabilities of their design through manipulative tasks, showcasing the technology’s ability to lift and maneuver rocks underwater. Such experiments affirm that the advancements announced in their publication can bridge the often-challenging interaction between robotic devices and aquatic materials.

Anticipated applications of the starfish-inspired underwater adhesion technology are vast and varied, indicating profound implications across several fields. With its adhesive properties functioning without traditional glues, the technology opens doors to precise chip transfers essential for MicroLED manufacturing. By enabling meticulous handling of components, the technology has the potential to enhance manufacturing processes, thereby supporting the production of brighter and more energy-efficient screens for an array of digital devices ranging from smartphones to large display units.

The healthcare sector could also see transformative changes thanks to this cutting-edge technology.
