Abstract

The design and prototype realisation of a complete radiotelemetry system for long-term monitoring of laboratory animals is described. The transmitter component is potentially implantable and transcutaneously powered using a single-component 200 kHz magnetic field. Monitoring of up to four data channels is possible using time-division multiplexing. The FM carrier is quartz crystal controlled to ensure long-term system stability and satisfy UK biomedical telemetry regulations. Implementation of the system would now require miniaturisation of the implantable transmitter component.
