Small radio transmitting devices and a receiving-recording system have been developed for the study of physiologic variables of interest to dental research. Frequencies above 100 megacycles are suitable radio carrier frequencies for transmission through biologic material, and considerable advantage exists at these frequencies over low-frequency transmitters owing to the small physical sizes of inductive and capacitive tuned circuit elements. Various construction technics and circuit designs have been explored, as have methods of fabrication of tooth-sized FMFM telemetry transmitters. A receiver-recorder system has been designed for the recording of such discontinuous or random events as total tooth contacts in a 24-hour period. Author
