Patent ID: 8583227

Claim:
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.
