Kind Code:
B2
Abstract:
A new type of pressure sensor is disclosed here. The sensor is composed of a pair of glass substrates and a ferroelectric liquid crystal which is interposed between the substrates and exhibits piezoelectric effect. Because of crystalline property in liquid phase, the piezoelectric medium can be easily disposed and aligned between the substrates in light of the orientation of the surface contiguous to the liquid crystal layer.
