1.The idea of a triboelectric nanogenerator (TENG) was first presented in scientific literature in 2012 [1], and is now considered the most promising technology for converting mechanical energy into electrical energy. In Teng devices, mechanical energy is converted into electrical energy by periodically connecting and separating two materials with different electron inclination (Shaematically shown in Annex 1).The TENG devices described in scientific literature have a significant drawback: Two separate and/or mobile and/or rigid mould parts are needed to prevent these energy installations from being integrated into bulk materials and structural elements. Similarly, the surfaces of individual parts of materials should be nanostructured to provide a large contact area. Nanostructuring requires difficult (complex) industrialisation methods.This project aims to create advanced TENG systems and innovative pieastomer nanocomposite capacitors and/or combinations of these two technologies for converting mechanical energy into electrical power.The functioning of the existing contact-separation TENG devices will be improved by using super flexible sponge structure elastomers, while using meso-grained materials in which each individual pore-remould be designed as a super-flexible sponge structure elastomers. The operational efficiency of the (enhanced) TENG developed by the project will be enhanced by the creation of hybrid systems with a piezoperable elastomer nanocomposite capacitor that multiplies the electricity generated by TENG by charging and discharging the capacitor before and after deformation respectively. It is planned that the resulting alternative and clean energy producing systems will be able to replace batteries used in low-energy sensors in the fields of health and care, environmental protection, infrastructure monitoring and safety.
