Our lab has developed multiple embedded sensors for monitoring different medical conditions. These embedded sensors are passively powered wireless sensors that can be integrated with medical devices such as suture anchors to measure tensile stress during soft tissue repairs, such as ligament and tendon surgeries. These innovative sensors are based on LCR circuits which can be interrogated wireless, allowing it to measure the mechanical environment while the devices remaining implanted without any active power source. These sensors are ideal for both short- and long-term implants. Our research has demonstrated its potential to improve the quality of surgical repairs and monitor implant integrity post-surgery.
