Power management architecture for smart hip prostheses comprising multiple energy harvesting systems

► A power management architecture is designed and tested to power a smart hip prosthesis implantable device. ► Energy is harvested from three independent micro-power generators that comprises the prosthesis system. ► Multiple energy sources are harvested to charge an ultracapacitor, as the system's main energy reservoir. ► Implant activation features enables continuous operation through its complementary inductive link. ► Experimental data shows that a Bluetooth low energy telemetry system can operate up to 50 s.
