An interdisciplinary team of students at the University of Waterloo has made significant strides in materials science by developing a tissue-like hydrogel for artificial muscles in soft robots. The initiative, led by Ph.D. candidate Negin Bouzari and supported by undergraduate students from various engineering fields, aims to simplify the programming of soft robotics. The research team discovered that by combining molecules with both positive and negative charges, they could create a hydrogel that exhibits unique bending and shape-changing properties when exposed to environmental triggers like pH changes or salinity. This innovative hydrogel can serve as an actuator, functioning as an artificial muscle for robots. Unlike traditional methods that require multiple fabrication steps, this new approach utilizes glass slides as programming tools, streamlining the process. The project underscores the value of interdisciplinary collaboration, as it brought together diverse expertise to solve complex problems. The findings were published in the Journal of Materials Chemistry A, with implications for non-invasive biomedical applications, particularly in areas like the gastrointestinal and reproductive tracts.
