We aim to fabricate multi-stacking graphene layers (MSGL) to convert surface energy to electrical energy as surface-energy generator devices (SEG). This device role employs movement of liquid in nano/micro-channels to induce charge on the surface of graphene. The SEG device consists of graphene sheets between two electrodes where one part of the electrodes covered with polymer is in solution. The MSGL are fabricated by stacking of many graphene sheets, which are synthesized from chemical vapor deposition (CVD). Mechanism of energy conversion and flow dynamics in nano/micro-channels will be studied by varying liquids with distinguished surface tension. Moreover, we expect to observe enhancement of power generation by the Marangoni effects. Since it is assembled from graphene, having hight surface area but very low mass, generated power density would be high. The device could produce comparable power density to SWCNT-based generator [1].
