Abstract
A two axis sensor is provided for detecting angular movement relatice to either of two mutually perpendicular axes. The device includes a two-axis sensor comprising an upwardly directed, spherically shaped common electrode, an upwardly directed spherically shaped insulating member uniformly spaced from the common electrode to form a cavity therebetween, the common electrode and the insulating member being sealed to each other about respective peripheries thereof, with a dielectric fluid contained in the cavity, a plurality of detecting electrodes provided on an underside of the insulating member, the detecting electrodes formed by a selectively applied conductive surface coating on the underside, and a device for detecting variations in capacitance proportional to movement of the sensor relative to each of two mutually perpendicular axes by reason of movement of the dielectric fluid within the cavity.
