518 The development of active actuator for artificial heart and its fluid characteristic

Abstract

A novel concept of using "peltier element" modules for heating and cooling the Shape Memory Alloy (SMA) is invesigated to examine the feasibility of reducing the response time for thermal cycling. Active profiles of SMA actuator are presented for each of the heating / cooling methods as well as estimate of total response time needed to complete an entire thermal cycle for artificial heart.
