Abstract:
1. A microstructure, comprising: a first substrate; a first buckled membrane, the first buckled membrane is connected to the first substrate, the first buckled membrane has a first curved shape, a first area, and has buckled along a first buckling direction; and a second buckled membrane, the second buckled membrane is connected to a second substrate, the second buckled membrane has a second curved shape, a second area, and has buckled along a second buckling direction, the second buckling direction is opposite to the first buckling direction, wherein the first buckled membrane and the second buckled membrane are in contact over a contact area, the contact area is less than the first area or the second area, the first buckled membrane has a first membrane stiffness when loaded over the contact area and displaced opposite to the first buckling direction, the second buckled membrane has a second membrane stiffness when loaded over the contact area and displaced opposite to the second buckling direction.
