Colorado makes breakthrough soft muscle for soft robots that is cheap, strong and effective
The newly developed hydraulically amplified self-healing electrostatic (HASEL) actuators eschew the bulky, rigid pistons and motors of conventional robots for soft structures that exceed or match the strength, speed and efficiency of biological muscle. Their versatility may enable artificial muscles for human-like robots and a next generation of prosthetic limbs.
"HASEL actuators synergize the strengths of soft fluidic and soft electrostatic actuators, and thus combine versatility and performance like no other artificial muscle before. Just like biological muscle, HASEL actuators can reproduce the adaptability of an octopus arm, the speed of a hummingbird and the strength of an elephant."
