A general-purpose implantable multichannel telemetry system for physiological research.

摘要: The majority of physiologically significant parameters can be accurately measured with relatively simple transducers and a minimum sophisticated electronics; such include temperature, pressure, electrical activity generally require less than 200 Hz bandwidth. In most experiments, however, measurements at multiple sites are needed to characterize fully particular response, the use totally implantable telemetry systems becomes attractive as problems percutaneous leads in conscious animals compounded proportion number sensors. These have been produced limited quantities because large components long assembly times necessary provide amplifications signal processing small package. A new six-channel system incorporates all on single integrated circuit, only one CMOS divider chain an transmitter required for support. This high level integration accelerates time increases reliability by minimizing interconnections. Such advancements essential before full potential realized. paper details performance this during initial applications requiring bioelectrical, or temperature telemetry.
