Device and method for generating electrical energy

摘要

A device for generating electrical current in the presence of ambient heat includes an intermediate layer having a predetermined electronegativity value interposed between a first outer layer and a second outer layer, in which the first outer layer has an electronegative value less than the intermediate layer, and the second outer layer has an electronegative value less than the first outer layer. The intermediate layer includes a first binder combination and a second binder combination. The first binder combination contains a polymeric binder and a first electronegative material. The second binder combination contains a polymeric binder and a second electronegative material. The first and second binder combinations have a predetermined electronegative value that is greater than said first and second outer layers. A method of making and a method of activating the device for the generation of electricity are also disclosed.
