Design and calibration of a microfabricated 6-axis force-torque sensor for microrobotic applications

F. Beyeler, S. Muntwyler, B.J. Nelson
2009 2009 IEEE International Conference on Robotics and Automation  
This work describes the design of a capacitive multi-axis force-torque sensor for the monitoring of forces in the sub-milli-Newton and sub-micro-Newtonmeter range.  ...  This force range makes it a valuable tool for microrobotic applications. The sensor is experimentally investigated and calibrated.  ...  For a full six-axis force sensor six position measurement would be sufficient, therefore one of the z-axis measurements is redundant.  ...
