PIEZOELECTRIC SENSOR AND PRESSURE DETECTION DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric sensor capable of performing position detection and load detection within the piezoelectric sensor.SOLUTION: A piezoelectric sensor 10 has a piezoelectric layer held between an upper electrode 12 and a lower electrode 13. At least one of the upper electrode 12 and the lower electrode 13 is provided with a plurality of electrode patterns. A load value is measured by detecting a charge generation amount, and a position where the load is applied is measured by determining an electrode in which the charge is generated.
