Simulated proton density in degradable biocomposite film-based flexible device. (a) Current-voltage (I-V) curves of degradable biocomposite film-based flexible device measured under different humidity conditions. (b) Schematic diagram of proton transition along a chain of hydrogen-bonded water molecules, as postulated to occur for the Grotthuss mechanism. (c) Electric potential and (d–g) proton density distribution in degradable biocomposite film-based flexible device under different humidity conditions. (h) Current change according to FEM modeling for degradable biocomposite film-based flexible humidity sensors compared with the experiment results (55-85%RH).
