Overview
The Telemetry Group is developing small, power efficient, wireless data acquisition systems that can be implanted for long term monitoring of physiological signals. A driving force has been our need to record sympathetic nerve activity which is small in magnitude, high in frequency content and measurement durations of a month are required. Our solution to this problem is a compact device capable of recording a wide variety of biopotential signals with bandwidths as high as 8 KHz. These devices are now supplied commercially through a spin-out company Telemetry Research Limited. Our focus is on power and development of new sensors. Inductive power transfer has been used to provide energy to an ECG telemetry system for a rat. New sensors are being investigated for blood analysis, blood flow and blood pressure. These devices are low cost, high volume, and have applications in diverse areas starting with the implantable animal monitoring market, moving into clinical monitoring and also adding versatility to other existing devices..
