In today’s increasingly technology-driven world, soft robots, medical devices, and wearable technology have become integral parts of our daily lives. These innovations offer enhanced functionality and greater adaptability, making our interactions with technology more seamless and natural. Recently, researchers at the Korea Advanced Institute of Science and Technology (KAIST) have made a groundbreaking development in this field: the creation of a fluid switch powered by ionic polymer artificial muscles. This remarkable invention operates at ultra-low power while generating a force that is 34 times greater than its weight.
The introduction of this fluid switch marks a pivotal moment in the realms of robotics and medical device technology. Unlike traditional fluid switches that are often limited by size and rigidity, the KAIST research team’s fluid switch overcomes these challenges, offering promising applications in various fields. With the ability to control fluid flow in multiple directions and initiate movements with exceptionally low power consumption, this development ushers in a new era of efficiency and versatility in soft robotics and related technologies.
At the forefront of this innovation is KAIST’s research team, led by Professor IlKwon Oh, who developed a soft fluidic switch that operates on ultra-low voltage. This groundbreaking invention stands out from conventional motor-based switches due to its flexibility and compact size, making it ideal for narrow and confined spaces. Powered by artificial muscles that imitate the natural movements of human muscles, the switch responds to external stimuli such as electricity, air pressure, and temperature changes, providing precise control over fluid flow. This advancement represents a significant stride in the realm of soft robotics, offering a more adaptable and efficient solution for various applications.
Central to the functionality of this groundbreaking switch is the ionic polymer artificial muscle. Developed by the KAIST team, this muscle consists of metal electrodes and ionic polymers. Through the incorporation of a polysulfonated covalent organic framework (pS-COF), the muscle’s force-generating capacity is significantly enhanced. Despite its slender form, with a thickness of just 180 µm, this muscle can generate a force over 34 times greater than its weight. This exceptional characteristic allows for smooth and efficient movement even within ultrasmall electronic systems.
Professor IlKwon Oh highlights the immense potential of this technology in numerous industrial applications. “From smart fibers to biomedical devices, this technology has the potential to be immediately put to use in a variety of industrial settings,” he asserts. Furthermore, he notes that the applicability of this technology extends beyond soft robotics to include soft electronics and microfluidics based on fluid control. This versatility emphasizes the transformative impact of the electro-ionic soft actuator not only on soft robotics but on a wide range of technology-driven industries.
The development of soft fluidic switches powered by ionic polymer artificial muscles is an exciting advancement with vast implications for the robotics field. As these innovations continue to evolve, we can anticipate more flexible, efficient, and accessible technology solutions that will shape our everyday lives.
