Design and Fabrication of a Novel 3-Dimension Sensor and Its Application for Implant Mechanical Testing

A new three dimensions force sensor for the multi-function artificial joints simulator is proposed and developed. In this study, the main design and fabrication process is introduced. The different design factors are compared and their influence is also discussed. Furthermore, the relative solutions to the problem are analyzed. By FEA analysis, the sensor is optimized, and the results show that the three dimensions force sensor performance is accurate and reliable. The 3-D sensor can meet the requirements of the friction measurement in the multi-function tribological simulator.
