PT4.292 - An implantable ultrasonic sensor for continuous and wireless monitoring of tissue strains

Implantable devices for continuous, wireless monitoring of tissue rehabilitation are crucial for personalized health.Traditional electronic sensors, though small and flexible, struggle with biomechanical matching, biodegradability, biocompatibility, and wireless monitoring.Here, we introduce an electronics-free implantable strain sensor using ultrasonic metagel for continuous monitoring of wound rehabilitation.Tested on porcine tendon and wounded tissue in live pigs, the metagel monitors tissue rehabilitation continuously and wirelessly.
