Title: Electrostatic capacitance type sensor

IPC: G01L1/14
Filed: 2003-06-12
Abstract: <P>PROBLEM TO BE SOLVED: To reduce the hysteresis of an output signal corresponding to the capacitative element of an electrostatic capacitance type sensor.  <P>SOLUTION: The capacitative element is constituted between a displacement electrode 30 and capacitative element electrodes E1-E5. When an external force is applied, the displacement electrode 30 is displaced to make contact with a reference electrode E0 retained in a grounding potential, and then displaced while keeping the contact state with the reference electrode E0. When the displacement electrode 30 is displaced to change the clearance with the capacitative element electrodes E1-E5, the capacitance value of the capacitative element is changed, and the force is recognized based on this change. Since the displacement electrode 30 is kept in an insulating state, no voltage is applied to the capacitative element when the displacement electrode 30 is not in contact with the reference electrode E0. Accordingly, the charge quantity stored in the capacitative element is ignorably small, and the output signal is stabilized in a fixed magnitude.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
