Radio telemetry system for obtaining body temperature during simulated diving to 1000 FSW

An implantable radio telemetry system for transmitting deep body temperatures from dogs subjected to hyperbaric conditions was designed and tested. The design was adapted from a transmitter described by J. L. Riley, and was successfully tested both in vitro and in vivo to a simulated depth of 1000 FSW. Circuit schematic, printed circuit layout, and component layout are given.
