Wirelessly Powered and Modular Flexible Implantable Device
Published in 2020 27th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2020
This paper introduces a novel configuration for a wirelessly powered and modular implantable device, fabricated using flexible electronics.
The neural implant, which is based on Wireless Power Transfer, comprises a receiver antenna, a power management circuit, and a shank for power transmission, recording, and stimulation. The key innovation lies in its modularity, which enables two distinct configurations, allowing for customization to different shank lengths or antenna designs.
The research highlights that the main advantage of this approach is the enhanced long-term biological viability of the implant. This improvement is achieved by reducing the mechanical mismatch between the brain tissue and the device. The electronic design features a modular structure consisting of three sections: Antenna, Conditioner Circuit, and Shank.
