Abstract

1,097,123. Semiconductor strain gauges. ETHER ENGINEERING Ltd. March 15, 1965 [March 18, 1964], No. 11522/64. Heading H1K. [Also in Division G1] A strain gauge element has a plurality of integral elongate strain members extending from a common point and each of which in use is bent about an axis transverse to its length by a load applied to the common point by a diaphragm or a seismic mass. Each strain member is shaped so that along at least part of its length at least one of its transverse dimensions decreases with increasing distance from the common point. This tends to even out the strain applied to a transducer element bonded to the surface of the member or formed by diffusion of impurities into (silicon) semiconductor members. The gauges described are of two types. These are those having elongate members of uniform width but of varying depth and comparable devices in which the elongate members are of uniform depth but of varying width. The uniform device shown falls in the latter category. Transducers 19, 27 on the upper surface have counterparts on the lower surface. With all the gauges the transducing element may be connected in bridge circuits.
