By combining shape memory alloys with different hysteresis widths, complex actuator movements can be achieved. This contribution presents the properties of a combination of (Ti,Hf)Ni and Ti(Ni,Cu) films that enables the creation of an actuator with wave-like behavior. This wave-like behavior is convenient for walking and swimming microrobots. It can be initiated by simple heat pulses without the need for complex phase control. Deflection measurements of the corresponding cantilevers reveal the workability of such an actuator concept.
