Most modern biomedical implants implement some form of communications link between the implant and the outside world. This biotelemetry link has many requirements such as data bandwidth and power consumption. Designing an appropriate link that meets these requirements is one of the most significant engineering challenges associated with these implants. Communications methods that are currently used for this link include standard Radio Frequency (RF) approaches, inductively coupled approaches, and load modulation approaches. This thesis describes the development of a unique capacitance-based biotelemetry system for implantable applications. This system consists of two distinct parts: the implanted transmitter and the external body-mounted receiver. The prototype transmitter is based on a custom Application Specific Integrated Circuit (ASIC) fabricated using the AMI 1.5[mu] [micron] process. This ASIC encodes and transmits predetermined data packets by driving two electrodes in a slew-controlled manner, all contained within a biocompatible material. The receiver consists of charge-sensitive amplifier front end using a discriminator to distinguish individual bits. A Field Programmable Gate Array (FPGA) decodes the transmitted data and relays it to a PCbased LabVIEW interface. Test results using a saline-based human tissue model are presented.

Implantable sensing, whether used for transient or long-term monitoring of in vivo physiological, bio-electrical, bio-chemical and metabolic changes, is a rapidly advancing field of research and development. Underpinned by increasingly small, smart and energy efficient designs, they become an integral part of surgical prostheses or implants for both acute and chronic conditions, supporting optimised, context aware sensing, feedback, or stimulation with due consideration of system level impact. From sensor design, fabrication, on-node processing with application specific integrated circuits, to power optimisation, wireless data paths and security, this book provides a detailed explanation of both the theories and practical considerations of developing novel implantable sensors. Other topics covered by the book include sensor embodiment and flexible electronics, implantable optical sensors and power harvesting. Implantable Sensors and Systems – from Theory to Practice is an important reference for those working in the field of medical devices. The structure of the book is carefully prepared so that it can also be used as an introductory reference for those about to enter into this exciting research and developing field.

A Handbook on Biotelemetry and Radio Tracking presents the proceedings of an International Conference on Telemetry and Radio Tracking in Biology and Medicine, held in The University of Oxford, Oxford, U.K. on March 20–22, 1979. This book illustrates the advances connected with every aspect of biotelemetry and radio tracking. Organized into five parts encompassing 101 chapters, this compilation of papers begins with an overview of the method that allows assessment or control of biological parameters from animals, subjects, and patients with comparatively little disturbance and restraint. This text then examines radio telemetry as a system for telemetry or communications over great distances. Other chapters consider better transmitter design and construction of radio tracking. This book discusses as well telemetric measurements of hemodynamic response to driving in coronary patients. The final chapter deals with the study of the coastal movements of Atlantic salmon tagged with ultrasonic transmitters. This book is a valuable resource for biological researchers and ecologists.

A CMOS Self-Powered Front-End Architecture for Subcutaneous Event-Detector Devices presents the conception and prototype realization of a Self-Powered architecture for subcutaneous detector devices. The architecture is designed to work as a true/false (event detector) or threshold level alarm of some substances, ions, etc... that are detected through a three-electrodes amperometric BioSensor approach. The device is envisaged as a Low-Power subcutaneous implantable application powered by an inductive link, one emitter antenna at the external side of the skin and the receiver antenna under the skin. The sensor is controlled with a Potentiostat circuit and then, a post-processing unit detects the desired levels and activates the transmission via a backscattering method by the inductive link. All the instrumentation, except the power module, is implemented in the so called BioChip. Following the idea of the powering link to harvest energy of the magnetic induced link at the implanted device, a Multi-Harvesting Power Chip (MHPC) has been also designed.
