ABSTRACT OF THE DISCLOSURE A semiconductor accelerometer comprises mass means responsive to an impact for causing displacement from an initial position, support means surrounding the mass in spaced apart relationship therewith for defining gap therebetween, flexure means for connecting opposing edges of the mass to the support means and permitting displacement of the mass in response to the impact, the flexure means thus forming accelerometer body assembly formed of a semiconductor together with the mass and the support means, a plurality of pairs of stress detective elements, each of which is responsive to an impact originated stress for varying an electrical characteristics, respective pairs of the stress detective elements being arrange in symmetry relative to the center of the mass means, and each pair of stress detecting elements being arranged on the accelerometer so that both stress detecting elements are subject to the same mode stress in response to exertion of a specific direction of impact and to a difference mode of stress in response to exertion of an impact in the direction other than t specific direction for mutually cancelling variation of electric characteristics, and a circuit means for forming a Wheatstone bridge circuit with incorporating each pair of stress detecting elements at each segment thereof.
