N2 - A new concept of a thermoelectric actuator comprised of shape memory alloy and Peltier elements has been proposed. The shape memory alloy is heated or cooled simultaneously by Peltier elements and the 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 developed active catheter, which can bend and twist according to the current supplied to the Peltier elements, shows the fast response and can be operated with less power consumption.
