Abstract
The invention relates to a micro reactor arrangement, particularly for a micro relay. It comprises a substrate ( ) with two thermomechanical micro actuators ( ). In response to thermal stimulation, the first micro actuator ( ) performs a movement in parallel with the substrate surface ( ), while the second micro actuator moves in a direction orthogonal on the substrate surface ( ). Both thermomechanical micro actuators are so disposed relative to each other that the first micro actuator ( ), in the extended state, reaches under the second micro actuator ( ). With these provisions, the first micro actuator ( ) can be maintained in this position without supply of power when the second micro actuator ( ) is de-energized. With the present micro actuator arrangement, one can achieve the advantages of a high activation force and long positioning travels of thermomechanical micro actuators for micro relays, without the necessity to supply energy for maintaining the individual switching states.
