Abstract:

A radiotelemetry system designed as a flexible monitoring instrument for use in the investigation of biosensors is described. The modular subassemblies of this telemetry system may be easily combined to yield either single or multichannel telemetry units capable of monitoring physiological variables. Physiological information is telemetered as a change in the pulse rate of a unijunction oscillator. The information pulses gate a radio frequency transmitter, normally a transmitter tunable from 88 to 105 megacycles, which is connected to a special belt antenna. The transmitted signal is received using a commercial receiver. Demodulating, averaging, and amplifying circuits reconstruct the physiological signal for graphic presentation as a strip chart recording on an oscilloscope picture. The telemetry system described is a simple, dependable, and low cost means for the monitoring of physiological variables. Author
