In this paper authors present development of a characterization process for Microcantilever based piezo-resistive force-sensor wherein fusion of real-time vision and force feedback has been used with a nanomanipulator (MM3A R ) system. The system works with MM3A nanomanipulator, it applies definite forces in range of 10-80 �N on the force sensor and resulting deflection produces voltage which is directly measured on oscilloscope. Deflection values have been recorded using images captured by CCD camera mounted on a light microscope. The sensor characterization is carried out which considers third order nonlinear behavior in cantilever based piezo resistive force sensor output. The sensor behavior has been studied using both linear assumption and third order nonlinear system, which shows upto 20% of output is produced by nonlinearity term. Therefore it is significant contribution in the sensor, which cannot be treated negligible. The sensitivity of force sensor found out 18.79mV=�N with linear model whereas with nonlinear model, Linear and Cubic coefficients are 14.75 mV=�N and 0.681 �V=�N3 respectively.
