Why aren’t Electro Active Polymers used to create exosuits or prosthetics instead of the traditional electric motors/actuators?

Question

Why aren’t Electro Active Polymers used to create exosuits or prosthetics instead of the traditional electric motors/actuators?

In: Engineering

Answer 1

Their actuation force is pretty weak, their have so-so environmental resistance, and I don’t think their max cycle lifetimes is nearly in line with traditional actuators.
