Abstract

PURPOSE: To obtain a prove which forms electro-signal responsing three dimensional motion of object, in simple consititution, by setting movable electrode which does mechanical motion responsing the motion of object and two pair fixed electrodes so as to sandwich the movable electrode in two axis drections.
CONSTITUTION: A pair of fixed electrodes Ef1, Ef2, which are set in parallel so as to sandwich a movable electrode Ev, constitute a pair of capacitors C1, C2 with cooperation, and this pair of variable caparitors C1 and C2 are constituted so as to do reverse motion each other, i.e., one of the capacitors C1 inverses the capacitance and the another C2 decrease the capacitance. Increase and decrease of theses capacitances are in inverse proportion with distance between the movable electrode Ev and the fixed electrodes Ef1 and Ef2. These pair capacitors are connected to each quartz oscillstor Xtal1, Xtal2 in series and to oscillators OSC1, OSC2 and each output is input to a mixer MIX and differential frequency signal Ed is output. By so doing, it enables to detect accurately and easily three dimensional motion of object.
