Light-Controlled Gel Could Benefit Soft Robots

Facebook Twitter LinkedIn Email Comments
BERKELEY, Calif., June 4, 2013 — Inspired by the way plants grow toward light sources, bioengineers at the University of California, Berkeley, created a hydrogel that flexes in response to near-IR laser light. The achievement could be a step towardadding softness and flexibility to robotics. “Shape-changing gels such as ours could have applications for drug delivery and tissue engineering,” said principal investigator Seung-Wuk Lee, associate professor of bioengineering. The material could also have future applications in the emerging field of soft robotics, which takes a cue from some of nature’s...Read full article
