Title:
RUB DETECTING SENSOR AND ELECTRONIC INSTRUMENT
Document Type and Number:
WIPO Patent Application WO/2018/131674
Kind Code:
A1
Abstract:
Provided is a rub detecting sensor capable of detecting the direction of a rubbing operation using a simple structure that is not bulky.
This rub detecting sensor is provided with: a first region (R1) which accepts a pressing operation from a user; a second region (R2) at least part of which is adjacent to the first region (R1) and which accepts a pressing operation from the user; a piezoelectric element (10) which outputs electric potentials having respectively opposite polarities when a pressing operation is accepted by the first region (R1) and when a pressing operation is accepted by the second region (R2); and an operation detecting unit (18) which detects a rubbing operation on the basis of states of detection by the piezoelectric element (10) in the first region (R1) and the second region (R2).
