Finally, an application is presented where electrical energy is generated inside a prototype TKR implant. All of the above works except [12] use in-vivo sensors for research purposes only. In contrast, our work aims to use selfpowered sensors in real-world clinical implants. Compared to [12], smaller PZT elements are used in our work, which specifically addresses the problem of limited space available inside an implant. Hence it presents a more practical application scenario. In the application of TKR, implant kinematics require that deflection of the bearing surfaces be small (
