Biomimetic reactions in conducting polymers for artificial muscles: sensing working conditions

IIn the dense gel that is the intracellular matrix forming part of living cells electrochemical reactions take place provoking the interchange of ions and water with the surroundings. Systems containing conducting polymers mimic this feature of biological organs. In particular, conducting polymers a...
