In the Autonomous Systems and Biomechatronics Laboratory (ASBLab), a concept of a novel three-component piezoelectric force sensor has been designed in order to achieve the requirements for meso-milling applications. The sensor is designed to have a minimum resolution of 10 mN, an operational frequency bandwidth of 8.3 kHz and a measuring range of up to 10-15 N. This thesis focuses on the development of a prototype of the force sensor design, including the design for physical development of the force sensor, the development of its amplification system and its calibration methodology. The result from the calibration test demonstrates that the prototype sensor developed has the required specifications for the meso-milling applications.
