Project Description:

Twisted coiled polymer actuators (TCPAs) are an emergent type of thermomotive artificial muscle that have recently biome-chanically surpassed human skeletal muscles (HSM). Post annealing, an increase in temperature causes a twisted elastomeric fiber to untwist, but when coiled it dissipates the torsional energy through up-coiling to obey the law of topological invariance. This all results in tensile contraction (TC) and Tensile Stress (TS). We are trying to optimize the polymer material properties to improve action.
