Abstract

Actuator comprises at least one layer, composed of nanoporous carbide derived carbon, and containing an electrolyte, such as ionic liquid. The actuator extends linearly when voltage is applied to the actuator. Nanoporous carbide derived carbon layer preferably contains 80 to 100 volume percent of a material having an average pore size is less than 1 nanometer and at least 50 per cent of the total pores volume is from the pores with the size less than 1.1 nanometers. Actuator may comprise two layers of nanoporous materials, separated by membrane of polymer material.
