Title: Contact force and tactile sensor using piezoelectric vibration having three-terminal structure
Inventor: IMAHASHI TAKUYA
IPC: G01L1/10
Filed: 1994-03-31
Abstract: PURPOSE:To obtain a contact force and tactile sensor using a piezoelectric vibrator having a three-terminal structure which has a strong noise resistance and a high resolution and can be made small in size. CONSTITUTION:When an oscillation circuit 102 makes oscillation, vibration is generated under an electrode 103a by a reverse piezoelectric effect. Under an electrode 103b, vibration caused by the vibration generated in an electrode 103c and propagated therefrom is present, and that vibration becomes piezoelectric vibration in the electrode l03b and an electric charge is generated. By the propagation of the vibration from the electrode 103c to the electrode 103b, at this time, signals other than the one near a resonance frequency f0 of a three-terminal piezoelectric vibrator 103 are filtered and removed. When noise comes in the oscillation circuit 102, for instance, a signal in a band narrower than the band of DELTAf can be taken out of a signal outputted from an output terminal 106, while the noise in the band of DELTAf comes in a signal outputted from an output terminal 107.
