Thermal actuator for e.g. microfluidic components, comprises alternating layers of two different materials

The actuator (1) comprises alternating layers of a first and second material (3, 4). The actuator comprises an actuator portion capable of a predetermined displacement (a) dependent upon a control signal. The two materials cooperate in response to this signal and preferably have two different expans...

Beschreibung
Zusammenfassung:	The actuator (1) comprises alternating layers of a first and second material (3, 4). The actuator comprises an actuator portion capable of a predetermined displacement (a) dependent upon a control signal. The two materials cooperate in response to this signal and preferably have two different expansion coefficients, the signal being a heating of the actuator.
