Peano-HASEL actuators that mimic natural muscle

The Keplinger Research Group at the University of Colorado Boulder has developed soft electrically powered artificial muscles which feature characteristics remarkably similar to those of natural muscle. These devices, termed Peano-HASEL (Hydraulically Amplified Self-healing ELectrostatic) actuators, can generate powerful linear contraction, operate at high speeds, and demonstrate high optical transparency. Additionally, these soft devices can simultaneously function as actuators and sensors that are capable of precise and life-like movement while self-sensing their position. Peano-HASELs are constructed from inexpensive thin-film plastics, the same material chip bags are made from. Currently, actuators can be made in the lab for less than 10 cents per device, using industrially compatible fabrication methods.
