"generating electricity based on the interaction between water and materials... flexible adjustable hydrovoltaic asymmetric sandwich structure device powers micro-electronics... only consumes renewable energy, low-cost, non-polluting, highly sustainable, and high power density.. working principle depends on evaporation- rather than streaming-potential... multiple device integration enables driving electronic devices for correct operation and energy storage... charges commercial button-type lithium batteries"
