MIT bio-inspired microactuator harvests energy from water vapor

2013-01-17 20:07:39| Extremetech

A sponge absorbing water from the air does not at first appear to be a promising powerplant for a microactuator, let alone one that could rival the speed and power of our own muscle. A research group at MIT has recently built a polymer actuator that runs off of water vapor alone, yet has the performance of actuators that are powered by more energetic sources like heat or light.
