Title:
SURFACE FORCE MEASUREMENT METHOD AND SURFACE FORCE MEASUREMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/115634
Kind Code:
A1
Abstract:
The present invention provides a method and a device for measuring force (hereinafter referred to as surface force) acting between two substance surfaces. A surface force measurement method comprises: moving an object to be measured (1) to a probe (4) until the probe (4) is adsorbed to the object to be measured (1); thereafter applying a load to a support member (6) by an electromagnetic force generator (20) in a direction in which the probe (4) separates from the object to be measured (1) while gradually increasing an electric current to be supplied to the electromagnetic force generator (20); acquiring the value of the electric current being supplied to the electromagnetic force generator (20) when the probe (4) has separated from the object to be measured (1); and converting the electric current value into surface force acting between the probe (4) and the object to be measured (1).
