Artificial Muscles: A Step Towards Sustainable Soft Robotics
Introduction: Advancements in Artificial Muscles
Artificial muscles are a rapidly evolving technology that has the potential to revolutionize the capabilities of robots. These muscles mimic the functionality of living organisms, opening up new avenues for robots to interact with and shape the world around us. From wearable devices that enhance physical abilities in old age to search and rescue robots that navigate challenging terrains, artificial muscles have the potential to make a significant societal impact.
The Importance of Sustainability in Soft Robotics
While artificial muscles can have a positive impact during their use, it is crucial to consider their environmental impact once they reach the end of their lifespan. In recognition of this, an international team of researchers from the Max Planck Institute for Intelligent Systems (MPI-IS), Johannes Kepler University (JKU), and the University of Colorado (CU Boulder) came together to design a fully biodegradable, high-performance artificial muscle.
A Breakthrough in Biodegradable Technology
The team’s groundbreaking research focuses on developing sustainable materials for soft robotics applications. The researchers successfully created a biodegradable artificial muscle using gelatin, oil, and bioplastics. They demonstrated the potential of this technology by animating a robotic gripper, which could be particularly useful in single-use deployments such as waste collection.
Biodegradability for Environmental Impact Mitigation
One of the key features of these artificial muscles is their ability to fully biodegrade within six months when disposed of in municipal compost bins. This sustainable solution addresses the urgent need for environmentally friendly materials in the field of soft robotics. By utilizing biodegradable parts, these robots can contribute to an eco-friendly future by becoming compost for future plant growth instead of accumulating in landfills.
The Role of HASEL in Soft Robotics
The researchers built an electrically driven artificial muscle called HASEL (Hydraulically Amplified Self-Healing Electrostatic). HASELs are oil-filled plastic pouches partially covered by a pair of electrodes. Applying a high voltage across the electrode pair generates a force that pushes oil to an electrode-free region, causing the pouch to contract like a real muscle. The materials used in HASELs must be electrical insulators to withstand the high electrical stresses generated by the charged electrodes.
Developing Biodegradable Electrodes
The project faced the challenge of creating conductive, soft, and fully biodegradable electrodes. The researchers at Johannes Kepler University developed a recipe using a mixture of biopolymer gelatin and salts that can be directly cast onto HASEL actuators. This formulation offers readily available components and an accessible fabrication strategy, making it suitable for high-performance applications and serving as a building block for future biodegradable materials.
Finding Suitable Biodegradable Plastics
Another challenge was finding biodegradable plastics that exhibit the necessary properties for HASELs, such as degradation rate and mechanical strength. The researchers discovered several bioplastics that showed good material compatibility with gelatin electrodes and sufficient electrical insulation. Remarkably, the biodegradable artificial muscles made from specific material combinations demonstrated resilience, withstanding 100,000 actuation cycles at several thousand volts without electrical failure or loss of performance.
Promoting Sustainability in Artificial Muscle Technology
The outstanding performance of this new biodegradable materials system incentivizes the robotics community to consider the use of sustainable materials in building robots. With the successful integration of bio-plastics, other material scientists may be inspired to create new materials with optimized electrical performance. This research project marks a significant step towards a paradigm shift in soft robotics, where biodegradable materials play a central role in building sustainable robot technologies.
Conclusion: Paving the Way for Sustainable Soft Robotics
The team’s research project showcases the potential of biodegradable materials in soft robotics. By developing a fully biodegradable, high-performance artificial muscle, the researchers have highlighted the importance of sustainability in the field. The use of biodegradable materials not only mitigates the environmental impact of robots but also promotes a greener future by encouraging the adoption of eco-friendly technologies. As green technology continues to gain momentum, the integration of biodegradable materials in soft robotics represents a crucial step towards a more sustainable and environmentally conscious future.
