Paper Abstract

There have been several cantilever-based actuators which provide movement in a direction transverse to the length of the cantilever. Here we describe a novel actuator which gives movement in the same direction as that of the length of the element. This is achieved by a curling up action of a bimetal like 'metal on silicon dioxide' straight element due to large differences in the coefficients of linear expansions and the high temperature which is obtained during the metal deposition.
