Abstract
Electricity, as old as it is, is still difficult for many regions of the world to attain. Research on accessible and efficient devices such as triboelectric nanogenerators (TENGs) tackle this issue as they can be made from the simplest of materials while remaining affordable. The purpose of the experiment was to evaluate the differences in millivolt (mV) outputs of three TENG types: contact separation, lateral sliding, and single electrode mode. It was hypothesized that contact separation mode would perform the best because it had the most direct electron diffusion. The prototypes were restricted to a 30.1 cm by 30.4 cm by 6.0 cm area to imitate the area of one floor tile with a TENG circuit. The single electrode TENG had the lowest mean output of 1.6 mV. The lateral sliding mode performed considerably better, with a mean output of 2.5 mV, and the contact separation TENG performed the best, with a mean output of 3.2 mV. A one way analysis showed that the TENG’s outputs were significant, F(2,87) = 188.92, p <.0001. Post hoc analysis using a Tukey test showed the single electrode mode TENG (M = 1.6, SD = 0.11) was significantly different from the contact separation mode (M = 3.2, SD = 0.40) and lateral sliding mode (M = 2.5, SD = 0.25), but the contact separation mode TENG and lateral sliding mode TENG did not differ notably. Overall, the TENGs are low output devices but have a promising future due to their compactness and affordability.
