In the research field of several biomedical disciplines a major need exists for reliable and implantable telemetry sensor systems. Apart from the demands for small size, light weight and long operational lifetime, the sensor systems should preferably also be flexible, versatile and intelligent. As a follow-up of previous work, a novel and more powerful transponder is developed, specifically tailored for applications in large-scale animal husbandry. It is a read-write telemetry device based on a microprocessor configuration, containing a dedicated sensor interface chip (SIC), SMD thermistor and subminiature capacitive accelerometers.
