In order to fabricate an integrated miniature six-axis force sensor, a novel integrated strain gauge is presented. This strain gauge is made up of six sensitive grids. By attaching the strain gauge on a thin-walled elastic cylinder, a six-axis force sensor is obtained. The signal conditioning circuit and digital circuit are illustrated. Utilizing the small digital signal processor and the rigid-flexible printed circuit board, all circuits are integrated into the sensor body. The static and dynamic calibration of the force sensor is presented, and the results are discussed.
