Summary

A new thermoelectric actuator concept comprised of shape memory alloy and Peltier elements has been proposed. The shape memory alloy is heated or cooled simultaneously by Peltier elements and an efficient and quick movement can be achieved. The thermoelectric actuator has been applied to a medical catheter. The operating principle and mechanism of the catheter are described. The active catheter that has been developed can bend and twist according to the current supplied to the Peltier elements, shows a fast response and can be operated with less power consumption.
