Laser powered miniature bionic devices
Grant number: LP160101052 | Funding period: 2016 - 2019
This project aims to develop a laser-based system to wirelessly power and control implantable medical micro-devices. Very-large-scale integration technology has miniaturised microelectronic medical implants, but energy systems have not shrunk; the wireless power/data interface is most of the implant’s volume. This project intends to develop an optical power/data interface to achieve high power density transfer to a miniaturised retinal implant housed entirely within a single self-contained transparent diamond capsule without any external lead wires. This safe and robust power/data delivery will exploit the outstanding transparency, biocompatibility and biostability of diamond encapsulation, ..View full description
