1. An electrochemical capacitor for use with a biofilm, the electrochemical capacitor comprising a first electrode coupled to a first porous layer, a second electrode coupled to a second porous layer; and an electrolyte provided between the first porous layer and the second porous layer; wherein at least one of the first porous layer and the second porous layer comprises a plurality of cavities adapted to receive redox active metabolites produced by the biofilm; wherein the electrochemical capacitor comprises a pseudocapacitance and a double-layer capacitance; and wherein when the biofilm grows between first and the second electrodes the first porous layer stores charges to charge the electrochemical capacitor.
