Abstract
A six channel FM/FM physiological telemetry system was designed to measure two surface temperatures, an internal temperature, the respiration rate, and position and muscle spasm of a paralyzed patient. The system has since been adapted to permit the measurement of pulse rate. Tunnel-diode subcarrier oscillators operating from a constant-current source provided excellent temperature and long-term stability while permitting a complete transmission package with size 0.6×2.5×2.5 inches and weight 15 gm. A compatible transistorized receiving system was also constructed.
