Abstract
Abstract A communications device arranged to be worn in intimate contact with the body of a user and without interference with bodily movements includes a radio transmitter and receiver for communicating with a remote station. The transmitter includes means arranged therewith and operative in conjunction with the body of the user for providing a relatively high transmitting frequency range. The device is miniaturized so as to provide predetermined transmitting and receiving circuit characteristics and is encapsulated so as to be essentially floatable, resilient and waterproof whereby it is rendered suitable outdoor activities such as sports and the like.
