Paper Abstract
Measurement of periodical contact force of the tapping stylus is very important for performance evaluation of soft material profilometry. So far, simulations are perfomred to estimate the force, and force calibration cantilevers are used to measure small contact force of AFMs. Since the tappign stylus uses larger tappign force compared to AFMs, micro cantilevers made of glass are developed for the force measuremetn of range from mN to μN.The levers are calibrated by using a standard cantilever made of silicon,which is fabricated by a micromachining process. A laser interferometre system is used for the calibration of glass cantilever spring constant. A laser Doppler vibrometer is used to measure the velocity of the cantilevers, and the force is estimated from the velocity signal by an integration.
