Document Type and Number:
WIPO Patent Application WO/2013/061356
Kind Code:
A1
Abstract:
Provided is a highly sensitive small slip sensor, which detects slipping of an object. A slip sensor (7) has: an oscillating section (6), which has a piezoelectric film (4) and a protecting section (2) covering the piezoelectric film; and a holding section (1), which holds the oscillating section (6). The oscillating section (6) contacts an object, and detects, as slipping, signals generated due to oscillation of the oscillating section (6). The piezoelectric film (4) is disposed by being displaced from the neutral axis of the oscillating section (6) such that the piezoelectric film (4) sufficiently expands and contacts.
