Would connecting several together then still produce more current? Because I'd assume that all the pieces of infected wood would have to be moving at the same time to generate friction. > "Moreover, we were able to significantly increase the maximum output current (≈ 205 nA) by connecting 30 wood sponges in parallel to each other, making a demonstrator suitable for wooden tables or floors." which is at 0.69V
