Abstract

Access to electricity in underdeveloped communities is particularly crucial in improving the living standards of people and alleviating poverty by promoting sustainable development. This study deals with the exploration of incorporating wood-plastic composite (WPC) – specifically wood pulp (W) and high-density polyethylene (H) – into triboelectric nanogenerator (TENG) flooring system to convert mechanical energy to electrical energy, promoting sustainable energy, reducing greenhouse gas emissions, improving the quality of life, and serving as feasible flooring tiles. Two types of TENG tiles were prepared by using different WPC ratios: 30W:70H and 70W:30H. A static bending test was conducted to assess the flexural strength of the TENGs, and a generated voltage test was performed by stepping on the TENGs several times and using a multimeter to measure the generated voltage. The 30W:70H TENGs had a significantly higher resistance to stress, with 18.0 MPa (SD=2.42), compared with that of 70W:30H TENGs, which had 8.07 MPa (SD=3.04) [t(8) = -5.74, p < 0.001]. However, the 30W:70H TENGs (overall M = 0.240 volts, SD = 0.051) generated slightly lower voltage than the 70W:30H TENGs (overall M = 0.265 volts, SD = 0.128), but no significant difference was concluded [t(8) = -0.415, p = 0.689]. The findings of this experiment allow for greater insight with respect to both compatibility and the potential applicability of the components in the real world. Other materials and parameters that could influence the performance of TENG tiles should be investigated, and the tiles should be tested under real-world conditions to obtain more accurate and practical performance data.

Abstract in Filipino [Abstrak]

Mahalaga ang pagkakaroon ng akses sa kuryente sa mga liblib na komunidad upang mapabuti ang antas ng pamumuhay at masolusyonan ang kahirapan sa pamamagitan ng sustainable development. Sinusuri sa pag-aaral na ito ang posibilidad ng paggamit ng wood-plastic composite (WPC)—partikular ang wood pulp (W) at high-density polyethylene (H)—sa isang triboelectric nanogenerator (TENG) flooring system upang ma-convert ang mechanical energy tungo sa electrical energy, na nagtataguyod ng sustainable energy, nagpapababa ng greenhouse gas emissions, nagpapabuti sa kalidad ng buhay, at nagsisilbi bilang angkop na flooring tiles. Dalawang uri ng TENG tiles ang inihanda gamit ang magkaibang WPC ratios: 30W:70H at 70W:30H. Isinagawa ang static bending test upang masukat ang flexural strength ng mga TENG, at isinagawa rin ang generated voltage test sa pamamagitan ng paulit-ulit na pagtapak sa mga TENG habang sinusukat ang boltahe gamit ang multimeter. Makikita na ang 30W:70H TENGs ay may mas mataas na resistance sa stress, na may 18.0 MPa (SD = 2.42), kumpara sa 70W:30H TENGs na may 8.07 MPa (SD = 3.04) [t(8) = -5.74, p < 0.001]. Gayunpaman, ang 30W:70H TENGs (overall M = 0.240 volts, SD = 0.051) ay bahagyang mas mababa ang nabuong boltahe kaysa sa 70W:30H TENGs (overall M = 0.265 volts, SD = 0.128), ngunit walang pagkakaiba ang natukoy [t(8) = -0.415, p = 0.689]. Batay sa mga resulta ng eksperimentong ito, mas malinaw ang pag-unawa sa pagiging compatible ng mga component at sa potensiyal na aplikasyon ng mga ito. Iminumungkahi ang pagsusuri sa iba pang materyales at mga parameter na maaaring makaapekto sa performance ng TENG tiles, gayundin ang pagsusuri ng mga ito sa aktuwal na kondisyon upang makakuha ng higit na eksakto at praktikal na datos.
