The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

© 2017 IEEE. This paper presents a design and implementation of an ultrasonic wireless energy transfer link to a visual cortical prosthesis implant device. Two ultrasonic transducers with 2 mm thickness and 12 mm diameter are implemented from scratch using Pz27 disc shape. The power transfer ultrasound link is demonstrated using 2 mm of tissue mimic in-vitro. The target voltage, required to operate the implant, of 1.8 V, 3.3 V and 5 V is achieved. The ultrasonic link and the overall system efficiencies are found to be 14.99% and 25% respectively. This system is found to be working in 36% of the FDA limit (720 mW/cm2).
