4 Single Hinge Bilayer Devices Flaps and Lids 

The most commonly employed type of actuator on the microscale is the bilayer, typically attached to a single rigid plate. The bilayer comprises the polymer and a metal film. Since the device is actuated electrochemically, a nonreactive noble metal is usually used, typically gold or platinum. The electrode serves both mechanical and electrical functions. It is the non-volume-changing layer that converts inplane strain in the conjugated polymer
