In this work, two different designs of triboelectric nanogenerators (TENGs) were
proposed, based on the vertical-separation contact mode. Each design was
fabricated in two different ways, the first one using only aluminum for the
electrodes. In the second one, aluminum and copper was used for the
electrodes. The first design is composed of two metal electrodes and
polydimethylsiloxane (PDMS) is used as a dielectric material. Three different
PDMS films were fabricated. The first one was fabricated without modifications
(used as reference). In the second one, a different volume of NaCl particles was
mixed with PDMS to create different pore ratios. In third one, SrTiO3
nanoparticles were added at different concentrations to the PDMS. All these
PDMS films were tested and compared. The film with a concentration of 10% of
SrTiO3 nanoparticles was the one that showed the best results in the TENG A-2,
it was observed an increment of 81.9% in the open circuit voltage, 78.4% in the
short-circuit current and 325% in the power output, when compared with the
PDMS film without modifications. The second part of the work was to improve
the design of TENG. A multilayer design was proposed that consisted of 3
triboelectric units, with six aluminum electrodes in total. Afterwards, functional
tests were performed by storing energy in a 100μF capacitor and then that
energy was used for powering three red LEDs. Finally the multilayer design was
adapted to a shoe insole to harvest the mechanical energy of humans while
doing activities such as walking, jogging and running. That energy was stored
and later used to power a portable calculator.
