Fig. 4. Characterization of the electrical properties of a snow-TENG in tapping and sliding scenarios.

Fig. 4.

(a) The testing setup showing a vertical linear motor, snow layer, and the fabricated snow-TENG. (b) Open circuit voltage, Voc, (c) Short circuit current Jsc, and (d) External load dependent peak power in the tapping scenario. (e) The charging profile of a 1 μF capacitor. (f) Voc during 8000 cycles of repeated loading and unloading, reflecting the stability of a snow-TENG device. (g) A visionary scene for a snowy location where a snow-TENG can be used for harvesting the energy of moving bicycles or cars. (h) A photograph of an energy-harvesting unit attached to a bicycle. Inset: An actual snow-TENG device on the wheel. (i) Measured Voc, (j) measured Jsc, and (k) external load dependent peak power in the sliding scenario.
