First Claim
Patent Images
1. An actuator element comprising:
- an organic ion exchange membrane;
a pair of thin metallic layer electrodes attached to opposite surfaces of said membrane;
means for fixing at least one part of said membrane to a stationary position wherein at least one part of said membrane is not fixed to the stationary position; and
means for applying an electric potential difference across said membrane in a water-containing state to bend and deform part of said membrane other than said at least one part fixed to a stationary position wherein at least one part of said membrane is not fixed to the stationary position.
