Wireless, Wearable NFC Enabled Power and Communication for Chronic Interfacing with Battery-Free Implants

Case ID:

This device will allow for long-term, secure, and reliable data collection from implantable biosensors in a simplified manner. An intended patient simply dons this device, and it will collect and transmit data indefinitely with no further interaction. This technology introduces a wireless, wearable, near-field communications (NFC)-capable device which can energize and control fully implantable, battery-free electronics. This device is embedded in a low cost, custom fitted, 3D-printed wearable mesh to ensure 24/7 communication with a target implant over periods of weeks to months. Onboard Bluetooth Low Energy and NFC capabilities enable secure, encrypted collection and transmission of biometric data. Relative to traditional battery-powered implants, our system supports higher sampling rates and complex implants with increased power demands, as there is no need for invasive surgery to replace a dead battery.

Implantable devices represent the future of remote medical monitoring and administration of both chemical and physical therapies to the patients. Although some of these devices are already in the market, the security mechanisms deployed inside them to withstand deliberate external influence are still decades away from the robust digital data security schemes employed in modern distributed networks these days. Medical data theft, spoofing, and disclosure pose serious threats that can ultimately lead to individual and social stigmas or even death. Along with that, the need to constantly replace batteries for these implantable devices may cause serious harm to those that constantly need surgery. Lastly, it could cause death if the battery fails or if it is not replaced in time.
