Micromuscle™

Micromuscle™

Micromuscle™ is an electroactive polymer (EAP) - a class of conducting polymers that can be electrically controlled to produce a swelling and contracting motion similar to human muscle.

Contolled Movement

When in an electrolytic liquid (bodily environment), low voltage (1-2V) applied to the polymer induces an electro-chemical reaction that makes the polymer switch between a deactivated state and an activated state. The state change in the polymer is characterized by the an ability to swell and contract, similar to a human muscle.

active steering & control
 

Controlled Release

Micromuscle™ technology can be utilized for the controlled release of substances within a polymer matrix. Substances can be incorporated into the polymer film during production and elute from the polymer film when a low voltage is applied. The applied voltage level can control the release profile of the substance. Substance release can be:
Controlled over a specified time period
Initiated and stopped on demand or within specific locations
Several substances can be eluted at a site
Sequenced elution of multiple substances is possible
