wave energy is a promising clean energy source, which is
abundant but hard to scavenge economically. Triboelectric nanogenerator
(TENG) networks provide an effective approach toward massive harvesting
of water wave energy in oceans. In this work, a coupling design in
TENG networks for such purposes is reported. The charge output of
the rationally linked units is over 10 times of that without linkage.
TENG networks of three different connecting methods are fabricated
and show better performance for the ones with flexible connections.
The network is based on an optimized ball-shell structured TENG unit
with high responsivity to small agitations. The dynamic behavior of
single and multiple TENG units is also investigated comprehensively
to fully understand their performance in water. The study shows that
a rational design on the linkage among the units could be an effective
strategy for TENG clusters to operate collaboratively for reaching
a higher performance.
