Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: "With the advent of manned space flight, the National Aeronautics and Space Administration (NASA) has conducted intensive investigations on the physiological makeup of the human body. The last decade has seen major advances in the use of radiotelemetry in physiological research. Revolutionary developments in microelectronics are making possible smaller telemetry systems that can be wholly implanted in laboratory animals. The NASA Ames Research Center has been in the fore-front of such research and has developed many implantable biotelemetry devices now considered by many as a standard method for monitoring physiological functions in animals. This report describes biotelemetry developments at Ames, tracing the evolution of concepts underlying the accurate and reliable biotelemetry systems of today. Such systems are described in sufficient detail for the reader to select designs to meet specific needs. Through its Technology Utilization Program, NASA strives to make the results of such work widely available for the use of those outside the aerospace community. This publication is one of a series intended to achieve those objectives."--Foreword.

Download or read book A Handbook on Biotelemetry and Radio Tracking written by Charles J. Amlaner and published by Elsevier. This book was released on 2013-10-02 with total page 825 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2011-02-17 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Inductive Powering by : Koenraad van Schuylenbergh
Download or read book Inductive Powering written by Koenraad van Schuylenbergh and published by Springer Science & Business Media. This book was released on 2009-05-31 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inductive powering has been a reliable and simple method for many years to wirelessly power devices over relatively short distances, from a few centimetres to a few feet. Examples are found in biomedical applications, such as cochlear implants; in RFID, such as smart cards for building access control; and in consumer devices, such as electrical toothbrushes. Device sizes shrunk considerably the past decades, demanding accurate design tools to obtain reliable link operation in demanding environments. With smaller coil sizes, the link efficiency drops dramatically to a point where the commonly used calculation methods become invalid. Inductive Powering: Basic Theory and Application to Biomedical Systems lists all design equations and topology alternatives to successfully build an inductive power and data link for your specific application. It also contains practical guidelines to expand the external driver with a servomechanism that automatically tunes itself to varying coupling and load conditions.
