For years, the challenge of powering the smallest implanted medical devices has held back the pace of miniaturisation in healthcare technology. Conventional battery formats have dictated both the size and complexity of these devices, limiting how deeply or delicately they can be placed within the body. That constraint is now beginning to dissolve, as Ilika’s solid state battery technology intersects with a novel charging method that turns sound itself into energy.
In collaboration with Piezo Energy Technologies, Ilika has demonstrated how its Stereax solid state batteries can be recharged wirelessly using directed ultrasound. The test scenario mimicked a medical implant recharging inside the body, showing that even at miniature scales, reliable power transfer is achievable through tissue using safe ultrasound fields.
Ilika plc (LON:IKA) is a pioneer in solid state battery technology enabling solutions for applications in Industrial IoT, MedTech, Electric Vehicles and Consumer Electronics.
