1. A triboelectricity powered electronic device assembly comprising a front part (200), a metal cover (50) 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
the metal cover (50) comprises a first end (90) and a second end (95), wherein the first end (90) is attached to the front part (200) of the assembly or a polymeric layer placed on a touch pad suitable for receiving a tapping mechanical input; and
the back part 400 comprises a second triboelectric nanogenerator (TENG) (600), a rubber material layer (32), a polymeric layer (28), a metal film (30) and a spacer layer (34),
wherein the metal film (30) is placed in the center of the back part (400) and is in communication with the metal cover (50),
the polymeric layer (28) of the back part is placed over the metal film (30), and the spacer layer (34) is located between the rubber material layer (32) and the polymeric layer (28) of the back part,
wherein outside contact with the polymeric layer (28) of the first part covering the touch screen receives 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.
