Actuators of Mica Layer Structures.

Abstract

A mechanism for a thermal actuating systems depends on the anomalously high thermal expansion of some crystals with layer structures. These have reversible thermal expansions in excess of 10(exp -1)/C; expansions of several thousand percent over a temperature range of a few hundred degrees centigrade have been reported. Stresses can be as high as 3 MPa, reversible thermal strains of approx. 5000%, and work densities greater than 10 MJ/cu meters have been obtained.
