Abstract : An electrocardiogram amplifier-transmitter was designed for use with dry electrodes for long-term heart rate monitoring on unrestrained subjects in orbiting laboratories. Extremely high input impedance compatible with dry electrodes and low power consumption was achieved by use of field-effect semiconductors in the amplifier input and in the transmitter. This device is being used on an experimental basis in space environmental laboratories. (Author)
