Memory and data communication link architecture for micro-implants

Abstract

With the growing need for the development of smaller implantable monitors, alternative energy storage sources such as high density ultra capacitors are envisioned to replace the bulky batteries in these devices. Ultracapacitors have the potential to be integrated on a silicon wafer, and have the benefits of an unlimited number of recharge cycles and extremely rapid recharging times. However, they present an essential challenge in that the voltage drops rapidly with energy drain. In this thesis, we explore a data storage memory that is compatible with ultracapacitor energy storage. In addition, we propose and demonstrate a low-power wireless link that exploits RFID techniques as a way of uploading the stored data.
