Development of Thermoelectric Actuators Applied to Artificial Heart Muscle
A novel concept for a thermoelectric actuator comprised of shape memory alloy (SMA) and Peltier elements has been proposed. The SMA is heated and cooled effectively by Peltier elements allowing quick movement to be achieved. The thermoelectric actuator has potential to apply an implanted artificial heart muscle. A one-dimensional numerical analysis of a time dependent temperature distribution along the prototype artificial heart muscle has been carried out in order to evaluate its performance. Experiments have been performed on a prototype muscle and the analytical result show good agreement with the experimental result.
