Abstract: Systems and methods are presented for a swallowable pH sensor made entirely of edible and digestible materials. A substrate is provided and an electrical circuit pattern is printed on a top surface of the substrate. The electrical circuit pattern includes a plurality of interdigitated electrodes and an antenna portion. The substrate is rolled into a cylindrical form such that the interdigitated electrodes are positioned on an outermost layer of the rolled substrate. The rolling of the substrate also causes the antenna portion of the electrical circuit pattern to form into a coil shape.

Abstract: Edible electrical systems containing food and/or food-based materials that possess electrical characteristics comparable or substantially equal to those of conventional materials used traditional electronic circuits and configured to include at least one of a capacitor, resistor, inductor, microphone, RF filter, pH monitoring device to collect information representing a living biological tissue from inside a body. A set of materials for use in constructing such edible electrical systems and methods of using such systems for acquiring such information. Edible electrical systems may be configured to be implantable.
