Abstract

The invention relates to a micro-driver in the technical field of MEMS, and belongs to a segmented-type double-layer membrane electric heating drive MEMS switch with a compliant mechanism. The switchcomprises a substrate, a segmented-type double-layer membrane electric heating drive unit, a base, and an electric contact unit. The double-layer membrane electric heating drive unit, the base and theelectric contact unit are located on a substrate, and the double-layer membrane electric heating drive unit is fixed on the base. The base is fixedly connected with the substrate, and the electric contact unit is disposed above the segmented-type double-layer membrane electric heating drive unit. The electric contact unit comprises a static contact point, a V-shaped support beam, a flexible spring, and an arc-shaped electric contact mass block. The V-shaped support beam is fixed above the segmented-type double-layer membrane electric heating drive unit, and the arc-shaped electric contact mass block is connected to the V-shaped support beam through the flexible spring. The static contact point is disposed above the arc-shaped electric contact mass block, and the static contact point cooperates with the arc-shaped electric contact mass block, and is connected with a peripheral circuit.
