Ball-electric power generator

Abstract

A ball-electric power generator is provided, in which triboelectric power can be generated by friction when balls made of one of triboelectric series having different shapes of spheres, sheets, rods, wires and the like move and hit layers or substrates made of one of the triboelectric series in a chamber defined by the layers or substrates and a spacer connecting the layers.

 a first upper layer configured to be electrically charged;   a first lower layer configured to be electrically charged;   at least one ball configured to be electrically charged;   at least one spacer connected to the first upper layer and to the first lower layer; and   at least one chamber defined by the first upper layer, the first lower layer and the at least one spacer,   wherein the at least one ball is configured to be moved inside the at least one chamber and to hit the first upper and lower layers, and thereby generating triboelectric charges.   
     
     
         2 . The ball-electric power generator of  claim 1 , further comprising a second upper layer integrally connected to an upper surface of the first upper layer and a second lower layer integrally connected to a lower surface of the first lower layer. 
     
     
         3 . The ball-electric power generator of  claim 2 , wherein each of the first upper layer and the first lower layer is an electrode layer configured to be positively charged and comprises one of Al, Fe. Ni, Cu, Ag, indium tin oxide (ITO), graphene or a carbon nanotube (CNT), and the at least one ball is configured to be negatively charged and comprises one of polytetrafluoroethylene, polydimethylsiloxane (PDMS), polyvinyl chloride (PVC), or polystyrene (PS), and wherein the first upper layer and the first lower layer are connected to one another through a wire, and thereby generating voltage due to an electric potential difference between the positively charged first upper and lower layers. 
     
     
         4 . The ball-electric power generator of  claim 3 , wherein each of the second upper and lower layers comprises polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyethersulfone (PES) or a metal template and is configured to support each of the first upper and lower layers. 
     
     
         5 . The ball-electric power generator of  claim 2 , wherein the first upper layer is an electrode layer configured to be positively charged, and the first lower layer and the at least one ball are configured to be negatively charged and comprise one of polytetrafluoroethylene, polydimethylsiloxane (PDMS), polyvinyl chloride (PVC), or polystyrene (PS). 
     
     
         6 . The ball-electric power generator of  claim 2 , wherein the first upper layer is an electrode layer configured to be positively charged, the first lower layer and the at least one ball are configured to be negatively charged, the first lower layer comprises one of polyethylene naphthalate (PEN), polyethylene terephthalate (PET), or polyethersulfone (PES), and the at least one ball comprises one of polytetrafluoroethylene, polydimethylsiloxane (PDMS), polyvinyl chloride (PVC), or polystyrene (PS). 
     
     
         7 . The ball-electric power generator of  claim 5 , wherein the second upper layer comprises one of polyethylene naphthalate (PEN), polyethylene terephthalate (PET), or polyethersulfone (PES), and the second lower layer is an electrode layer comprising one of Al, Fe. Ni, Cu, Ag, indium tin oxide (ITO), graphene or a carbon nanotube (CNT), and wherein the first upper layer and the second lower layer are connected to one another through a wire, thereby generating voltage due an electrical potential difference between the positively charged first upper layer and the second lower layer. 
     
     
         8 . The ball-electric power generator of  claim 2 , further comprising at least one inlet air tube configured to blow air into the at least one chamber so as to move the at least one ball inside the at least one chamber. 
     
     
         9 . The ball-electric power generator of  claim 1 , wherein the at least one ball is in a shape of one of wires, rods, cubes, or sheets. 
     
     
         10 . The ball-electric power generator of  claim 9 , wherein the at least one ball is in a size of nanometers to centimeters in length or height.
