Triboelectric Nanogenerator
Triboelectric nanogenerator (TNG) is environment friendly energy generator which using mechanical friction force. During the friction between two dissimilar materials, their surface becomes electrically charged. When TNG is separated, strong dipole moments are formed by generated surface charge, which induce electrons flow through the external circuit. There are four energy harvesting mode. 1) Vertical contact mode 2) Lateral sliding mode 3) Single electrode mode 4) Freestanding triboelectric layer mode. We have investigated all harvesting mode and material investigation. |

Piezoelectric Nanogenerator
Piezoelectric nanogenerator (PNG) is eco-friendly energy generator which using mechanical force. Piezoelectricity is defined as a change in electric polarization with a change in applied stress. Only, specific material which has non central symmetric crystal structure or ferroelectric property, generate energy during polarization change. There are two harvesting mode 1) Vertical force mode 2) Bending mode. We have researched all harvesting mode and material investigation. |
