The
triboelectric nanogenerator (TENG) has been proved to be a
green and efficient energy harnessing technology for electricity generation
from ambient mechanical motions based on its ability to leverage the
triboelectrification process. Enhancing TENG output performance through
rational structural design still triggers increasing research interest.
Here, we report a ternary electrification layered architecture beyond
the current binary TENG systems, with improved performance for mechanical
energy harvesting. Introducing a ternary Kapton layer into the traditional
binary electrification layered architecture of TENGs consisting of
copper and fluorinated ethylene propylene, yields a 2.5 times enhancement
of peak power output, representing a 6.29-fold increase compared
to the TENG composed of copper and Kapton. A wide-range of material
configurations were systematically tested using this ternary electrification
layered architecture to prove its practical effectiveness. The ternary
electrification layered architecture invented in this work provides
an alternative strategy to enhance TENG output performance, which
represents a solid step for TENGs application in high-performance
mechanical energy harvesting.
