Abstract: A bending sensor includes a flexible substrate made of polyimide; a laser-induced graphene electrode formed into a top surface of the flexible substrate; and first and second pads formed as a laser-induced graphene into the top surface of the flexible substrate, wherein the first and second pads are in electrical contact with the laser-induced graphene electrode. A bending of the flexible substrate and the laser-induced graphene electrode changes a resistivity of the laser-induced graphene electrode, which is indicative of an amount of bending.
