Abstract: The invention discloses a coupled power generating device, a power-generating insole and a light emitting shoe, the device comprising a column-shaped hollow shell, at least one group of magnetic induction coils that is provided on the outer wall of the column-shaped hollow shell, at least one removable column-shaped magnet that is provided on the inner wall of the column-shaped hollow shell, two triboelectric nano generating units that are provided at both ends of the column-shaped hollow shell. The coupled power generating device has the advantages of long service life, high output current, stable electrical performance and compact size.

Abstract: A method for making a shoe outsole comprises placing rubber against a coating of cured rubber cement on a segment of fabric, heating the rubber to a temperature below the melting points of the cured rubber cement and the rubber, but high enough to render the cured rubber cement and the rubber tackily adherent to each other and vulcanizing the rubber, thereby to adhere the segment of fabric to the rubber, and cooling the vulcanized rubber to form an outsole having an exposed ground-contacting surface that includes the segment of fabric.
