ELECTRICALLY VARIABLE SUSPENSION

摘要

A variable stiffness spring is provided that includes a dielectric diaphragm having a biaxially pre-strained film, where the dielectric diaphragm includes an out-of-plane stiffness at zero voltage, a first electrode disposed on a first side of the dielectric diaphragm and a second electrode disposed on a second side of the dielectric diaphragm, where the out-of-plain stiffness is relaxed by an applied voltage between the first electrode and the second electrode.
