Wireless implantable sensor platform

Surgical correction of scoliosis is a complicated mechanical process. Understanding the loads applied to the spine and providing immediate feedback to surgeons during scoliosis surgery will prevent overloading, improve surgical outcome and patient safety. Long-term development of residual forces in the spinal instrument after surgery with the continuously curvature changes over time have been unknown. The goal of the project was to develop a wireless implantable sensor platform to investigate the loads during and after surgery. This paper reports the accuracy of the sensing platform and the built in temperature sensor, the power consumption at different operation modes, the validation of the wireless communication and the discharge characteristics of a potential capacitive power module.
