Self-Powered Flexible Triboelectric Nanogenerators (TENGs) Based on Lateral Sliding Mode

A sliding triboelectric nanogenerator (TENG) was successfully designed, fabricated and tested at various surface contact displacements. The sliding-TENG consists of polyvinylidene fluoride (PVDF) and polyethylene terephthalate (PET) as bottom and top triboelectric layers, respectively. Glass was utilized as a supporting layer for the top and bottom triboelectric layers. Aluminum (AI) tapes were used as electrodes and sandwiched between glass and triboelectric layers. The performance of the fabricated TEN G was investigated in terms of open circuit voltage
$(\mathrm{V}_{\text{oc}})$
and short circuit current
$(\mathrm{I}_{\text{sc}})$
. TENG was evaluated by subjecting it to
$\sim 0.5$
m/s sliding velocity. The
$\mathrm{V}_{\text{oc}}, \mathrm{I}_{\text{sc}}$
, power and power density were measured and calculated as
$26.63 \mathrm{V}_{\text{pp}},8.08 \mu \mathrm{A},213.84\ \mu \mathrm{W}$
and
$8.55 \mu \mathrm{W}/\text{cm}^{2}$
, respectively.
