Abstract
A flexible electronic device includes a flexible electronic circuit and a flexible microfluidic sensor homogeneously integrated into the flexible circuit. The flexible sensor includes a flexible microfluidic structure, a first material, a second material, and an electrode arrangement. At least one of the first and second materials is a fluid. The structure defines at least one microfluidic chamber. The first and second materials are disposed in the chamber. The second material has a physical property and an electrical property different from the first material. The electrode arrangement includes at least one pair of electrodes spaced apart from each other with at least a portion of the at least one chamber located functionally directly therebetween such that at least one electronic property measured across the pair is based on a relationship between the second material and the electrode pair. The relationship is based on a physical condition of the microfluidic structure.
