(a) Photographic image of glowing 60 green LEDs driven by MPC-TENG. (b) The charging and discharging curves of the 10 μF capacitor charged by the MPC-TENG operating at 100 rpm. (c) Photographic images of a small-scale LCD timer powered using the energy stored in the 10 μF capacitor from the MPC-TENG at 100 rpm. (d) Complete setup of the MPC-TENG with attached wind cups and the air gun to harvest energy from the wind. Output (e) voltage and (f) current from the wind-driven MPC-TENG. (g) Schematic representation of the MPC-TENG integrated real-time alarm system. (h) Complete setup of the MPC-TENG attached to the Pelton wheel for hydrokinetic energy harvesting. (i) Output voltage and current from the hydrokinetically driven MPC-TENG. (j) Photographic images of digital thermometer powered using the energy stored in the 10 μF capacitor from the hydrokinetic MPC-TENG.
