Abstract

A colorimetric based sensor system includes a low power communication system to harvest energy from an interrogator and to broadcast information to the interrogator; a controller operatively connected to the low power communication system; a light emitter, operatively connected to the controller, to emit light; a light detector, operatively connected to the controller, to convert receive light into electrical signals; and a colorimetric based sensor, having a changeable color patch and in optical communication with the light detector and the light emitter, to measure a condition of an object of interest.
