Edible electronics components for biomedical applications

This paper presents design, production, testing and biomedical application of an interdigital capacitor made exclusively from edible materials (food). The purpose of this work is to demonstrate suitability of the sensor made from edible materials to detect pathological condition in the oral cavity. Interdigital capacitors were made on edible substrates such as biscuits, edible wax, and buckwheat tiles, while aluminum foil was used to make the conductive segments. The tests were performed at room temperature with the HIOKI IM3590 impedance analyzer device.
