Artificial fibular muscles with 20% strain based on polypyrrole-metal coil composites
A fibrous polypyrrole Pt/Ir-coil composite actuator, prepared electrochemically from a methyl benzoate solution of tetra-n-butylammonium bis(trifluoromethylsulfonyl)imide (TBATFSI), exhibited 20% electrochemical strain in propylene carbonate/water solution of LiTFSI. The artificial muscle fibre based on TFSI-doped PPy-Pt/Ir coil composite has reached the same level of natural muscle's strain.
