A NEW METHOD FOR THE MEASUREMENT OF SOFT MATERIAL THICKNESS

Thickness measurement of the soft materials presents some difficulties for standard stylus thickness measurement devices. Since the soft materials are deformed by the stylus due to the applied pressure, correct thickness measurement cannot be realized. Here, PDMS (Polydimethylsiloxane) is used as soft material for thickness measurement. By taking the replica of the soft material with liquid plastic which becomes rigid after curing, the depth can be measured easily via conventional stylus thickness measurement devices.
