Abstract
Disclosed herein is an inertial sensor. The inertial sensor includes a sensor unit provided with an electrode layer and including piezo-electric elements so as to detect a movement of a driving unit supported to be able to be displaced to detect inertial force; an IC electrically connected to the sensor unit; and a switch connected between the sensor unit and an IC so as to control electrical connection between the sensor unit and the IC.
Claims12
An inertial sensor, comprising:
- a sensor unit provided with an electrode layer and including piezo-electric elements so as to detect a movement of a driving unit supported to be able to be displaced to detect inertial force;
- an IC electrically connected to the sensor unit;
- and
- a switch connected between the sensor unit and the IC so as to control electrical connection between the sensor unit and the IC.
1 more element
A polling method, comprising:
- applying a switch-off signal to a package side switch control pad;
- applying high voltage to a package pad for polarization;
- performing a switch-on operation switching the switch into a switch-on state.
