The deflection and frequency analysis of the inhomogeneous silicon cantilever beam for microrelay

Abstract

The inhomogeneous silicon cantilever beam is used to the design of micro-relay, compared the properties with the inhomogeneous and homogeneous cantilever beam, we get the results as: the inhomogeneous cantilever beam has a lower drive power than that of homogeneous; when the same drive power, the pressure of the touch point of the inhomogeneous cantilever is greater than that of homogeneous, but the frequency of the inhomogeneous cantilever is lower than that of homogeneous. In some special cases, if the frequency and dynamic response does not require high precision, the inhomogeneous cantilever beam is a good choice; it can obtain a low driver power and high pressure on the touch point for the micro-relay. The deflection of and the frequency of the analysis of the inhomogeneous silicon cantilever beam for micro-relay is put forward in the paper.
