Flexible Wirelessly Powered Implantable Device
Published in 26th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2019
This paper presents a neural implant that is powered wirelessly using a flexible biocompatible antenna. We have applied a modular structure approach to the design of this device considering three modules of antenna, conditioner circuit and shank. The implant was fabricated using a flexible substrate of Polyimide and encapsulated by PDMS for chronic implantation. In addition, finite element method COMSOL Multiphysics simulation of mechanical forces acting on the implant and shank was carried out to validate a viable shank conformation-encapsulation combination that will safely work under operational stress with a satisfactory margin of safety.
