Abstract
A new type of a swallowable radio transmitter, ECHO CAPSULE, is described along with some clinical experiments. Unlike other similar capsules which have been reported, this capsule contains no battery and is energized from outside the human body. The energy is converted into dc by the transistor of the oscillator circuit itself, stored into a capacitor and then used as an energy source for the transmission of information on temperature, acidity or the like within the digestive tract.
