Abstract
This paper presents a micro-movement long-term monitoring system optimising the healing process of fractures. It focus in particular on the energy and data transmission path of the system. Continuous and accurate monitoring near the fracture zone of bones requires an implantable and low power consumption device. Additionally, the implant needs to be small in size. To serve as a long-term implant, no batteries are used due to their limitations in lifetime and power. Thus, the system is inductively powered based on the inductive coupling between an external and an internal coil. Monitoring is done by a miniature, capacitive accelerometer. Using a telemetric link the measured data stream is transmitted from the implant to a microcontroller, where the data is analysed.
