Fluid-driven artificial muscles

Proceedings of the National Academy of Sciences

Researchers report a fluid-driven artificial muscle that incorporates a compressible skeleton architecture, a flexible skin covering, and a fluid medium to direct the action of the muscle; the artificial muscle can be manufactured with various materials at multiples scales and execute motions including bending, contraction, and torsion, with the ability to contract more than 90% of its initial length and generate stresses of approximately 600 kPa, according to the authors.
