Abstract

A power and/or electricity generating source and/or component that is TENG-based, and that may be configured as an assembly and/or component for powering one or more electronic devices, is disclosed, A case, carrier or other carrying container, for example a case for a cell phone, ipad, electronic tablet, personal computer, or any similar device, that provides an electricity source to power the cell phone, ipad, electronic tablet, is disclosed. The energy generating carriers and/or containers and configurations thereof, also provide an electricity energy storage source. This electronic energy storage source may be incorporated within an electronic device itself, or may be incorporated within the case and/or covering. Upon walking or touching a surface of an electronic device, the power generating source will harness mechanical energy, and provide for the generation of electricity with the one or more TENG components (TESTEC) that comprise the energy generating unit. Metal particles (silver, copper, etc. nanoparticles) incorporated within and/or on polymeric layers and/or a film of the carrier and/or container assembly, are also provided, and provide for enhanced energy generating capacity of the energy generating and storage components described.

First claim

What is claimed is:

1. A triboelectricity powered electronic device assembly for an electronic device, the assembly comprising a front part ( 200 ), a side area ( 300 ), and a back part ( 400 ), wherein:
the front part ( 200 ) comprises:
a first triboelectric nanogenerator (TENG) ( 550 ), said first TENG comprising a single electrode TENG; and
a durable polymeric layer ( 28 ), said polymeric layer comprising a transparent area configured to cover a touch screen of an electronic device placed in the assembly; and

the side area ( 300 ) comprises a copper cover ( 50 ) and a polymeric layer ( 28 ), wherein said side area ( 300 ) is configured to cover a side of an electronic device placed in the assembly, and the copper cover ( 50 ) comprises a first end ( 90 ) and a second end ( 95 ), wherein the first end ( 90 ) is attached to the transparent area of the polymeric layer ( 28 ) of the front part ( 200 ), and the second end ( 95 ) is configured to cover the side area ( 300 ) of the assembly; and
the back part 400 comprises a second triboelectric nanogenerator (TENG) ( 600 ), a nitrile butadiene rubber (NBR) material layer ( 32 ), a polymeric layer ( 28 ), a copper film ( 30 ) and a spacer layer ( 34 ),

wherein the copper film ( 30 ) is placed in the center of the back part ( 400 ) and is in communication with the copper cover ( 50 ) of the side area ( 300 ) of the assembly,
the polymeric layer ( 28 ) of the back part is placed over the copper film ( 30 ), and the spacer layer ( 34 ) is located between the NBR material layer ( 32 ) and the polymeric layer ( 28 ) of the back part,
wherein outside contact with the transparent area of the polymeric layer ( 28 ) of the first part covering the touch screen of the electronic device generates mechanical energy, said first TENG ( 550 ) generating electrical energy from said mechanical energy, said electrical energy being delivered to an electronic device placed in the assembly, and
wherein frictional contact between the layers of the back part ( 400 ) produces motion generated energy, and the second TENG ( 600 ) generates electrical energy from said motion generated energy, said electrical energy being delivered to an electronic device placed in the assembly.
