Figure 1: (a) Open-circuit voltage and (b) short-circuit current peaks, (c) mean open-circuit voltage and (d) mean short-circuit current for the samples with different PDMS layer thickness. On the other hand, the minimum voltage (0.2 V) occurred for a PDMS thickness of 220 μm. The decrease of < VOC > with increasing thickness is apparently not in agreement with present TENG theories [17, 18]. It must then be related with intrinsic properties of the PDMS films, such as stiffness , hardness or roughness and their thickness dependence. The current has the opposite behaviour since, as the thickness increases, the current also increases, saturating at a value of ∼ 1.3 μA [Fig. 2(b)]. These results are in accordance with the theory of triboelectric nanogenerators [Eq. (3)]. We then measured the voltage and current from 100 to 1 GΩ , as seen in Figs. 2(a) and (b). Figure 2(a) illustrates the generated voltage and, for all samples, the voltage increased above a load resistance of 10 kΩ, tending to a constant value (open-circuit voltage). We also measured the current flowing in the circuit for the same range of resistances and noticed the opposite behaviour since, with increasing resistance, the current values decrease [Fig. 2(b)]. These results confirm that increasing the PDMS thickness leads to a decrease (increase) of the generated voltage (current). On the other hand, the maximum output power occurred for a PDMS layer thickness of 32 μm and has a value of 0.56 μW [which corresponds to a power density of 0.55 mW/m2; Fig. 2(c)]. Figure 2(d) shows the maximum generated power as a function of the PDMS thickness layer. It is possible to verify two different behaviours: up to 32 μm of PDMS, the generated power increases with increasing thickness (reaching a maximum value of 0.56 μW); from 32 to 220 μm the generated power decreases sharply, reaching a minimum value of 0.23 μW (which corresponds to a power density of 0.23 mW/m2) . 3PDF Image | Performance of PDMS-Based Triboelectric Nanogenerators
