Live Demonstration: Closed-Loop Wireless Power Transfer for an Implantable Drug Delivery System

The Nanochannel Delivery System (nDS) is a smart drug delivery implant featuring Bluetooth Low Energy that allows dosage control and temperature monitoring. Powered by a rechargeable battery, it offers a year-long device lifetime. This demonstration focuses on the closed-loop wireless charging system designed for safe and effective recharging during chronic, in-vivo experiments. The setup includes the implant, an external transmitter, a Raspberry Pi for real-time recharge management and data logging, and a PC for real-time data visualization. Visitors will watch a video of the system in use during animal studies and will wear the devices during the recharge process, simulating a clinical use.
