Beschreibung
Zusammenfassung:	An actuator system is provided that is configured to move a component relative to a base of the actuator system. The actuator system may include first and second actuating elements, each including two sections of material that are joined to each other and have different coefficients of thermal expansion. The two actuating elements may be configured such that if the temperature of one is increased it applies a force on the component in a direction that is opposite to the force applied by the other actuating element if its temperature is increased. The actuator system may further include at least one power supply configured to provide independently controllable heating to the first and second actuating elements.
