Title:
MEASUREMENT METHOD AND MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/171865
Kind Code:
A1
Abstract:
The present invention is for measuring both the vibration occurring in an object of measurement and the pressing force applied to the object of measurement without causing a measurement device to become more expensive. In the present invention, a pressing force generation unit 2 generates pressing force for pressing a piezoelectric sheet sensor 1 into an object of measurement 200. A vibration measurement unit 33 uses the piezoelectric sheet sensor 1 to measure the vibration occurring in the object of measurement 200. A pressing force measurement unit 31 measures the pressing force applied to the object of measurement 200 via the piezoelectric sheet sensor 1. A pressing force control unit 32 controls the pressing force generated by the pressing force generation unit 2 on the basis of the measurement result of the pressing force measurement unit 31.
