Experimental and theoretical analysis to investigate the effect of electrical performance of the C@PW-TENG device as a function of carbon mass-loaded on PWs and mechanical pushing force, its robustness behavior. (a) Weight percentage of carbon NPs loaded on different PWs and its sheet resistance. (b) Structure model and charge distribution across the individual components of the C@PW-TENG used for DDEF theoretical simulations. (c) Measured and (d) DDEF theoretical simulated electrical output I_SC curves of C@PW-TENGs as a function of carbon mass loaded on PWs. Measured electrical output (e) I_SC, (f) Q_SC, and (g) peak power of the C@PW-TENG at different mechanical pushing forces ranging from 10 to 30 N. (h) Robustness test of the device examined over several pushing cycles.
