University of Houston researchers developed an electrochemical actuator that uses specialized organic semiconductor nanotubes (OSNT). The device exhibits high actuation performance with fast ion transport and accumulation and tunable dynamics in liquid and gel-polymer electrolytes.

The actuator demonstrates low power consumption/strain, a large deformation, fast response, and excellent actuation stability.
