Capacitive Tilt Micro-Sensor

Division of the steregon (4π sr) into uniform sub-ranges is briefly discussed as a way of discrete determination of a tilt of an object. Mechanical designs of relevant patented sensors and their electronic circuits are considered. Then, a capacitive tilt micro-sensor is minutely presented. It features high reliability of operation and small dimensions. Its discrete principle of operation makes it possible to significantly simplify the signal post-processing. Results of experimental tests, where balls made of bearing steel with diameter of 2 to 5 mm were used are reported. A concept of a capacitive tilt sensor with analog output is proposed; such sensor determines the tilt not only in a discrete way but generates also a continuous output signal within sub-ranges of the steregon. Ways of further miniaturization of the micro-sensor are discussed.
