Patent ID: 8222796

Claim:
A micro-electro-mechanical device, comprising: a substrate with a main surface; an elastic member with a first end mechanically coupled to the substrate; a piezoelectric actuator with a first side mechanically coupled to the substrate, said piezoelectric actuator being positioned lateral to an unfixed region of the elastic member; and a transfer member mechanically coupling a second side of the piezoelectric actuator to the elastic member, wherein the elastic member is elastic in a direction vertical to the main surface of the substrate, wherein the first side of the elastic member is averted from the substrate, wherein the elastic member is a cantilever, wherein the elastic member comprises at least one of a notch, a groove, and a recess, wherein the transfer member is mechanically coupled to a first side of the elastic member, wherein the transfer member is coupled to a coupling point of the elastic member, and wherein the coupling point is remote from the first end of the elastic member.
