1. A system for detection of myoelectric activity, the system comprising:
- an ingestible identifier comprising;
a housing including a first electrode and a second electrode secured thereto;
a control unit electrically coupled to the first and second electrodes, wherein the control unit changes conductance between the first and second electrodes; and
a detection unit electrically coupled to the first and second electrodes, wherein the detection unit reads a surrounding environment to collect information, wherein electrochemical reactions between the first electrode and the surrounding environment and the second electrode and the surrounding environment respectively produce a voltage potential that powers the ingestible identifier such that the control unit switches the ingestible identifier between broadcast mode and detection mode; and
a second ingestible identifier configured to communicate with the ingestible identifier such that when the second ingestible identifier is in the broadcast mode the ingestible identifier is in the detection mode thereby allowing the ingestible identifiers to communicate.

Abstract
Portable electroviscerography systems are provided. Aspects of the systems include a body-associated receiver and an ingestible identifier unit, both of which are configured to detect visceral electrical signals. The system communicates with an extra-corporeal data processor configured to receive data from the body-associated receiver and generate and electroviscerogram from the received data. Also provided are methods of producing electroviscerograms using systems of the present invention.
