Science Daily April 3, 2024 Due to the advantages of simple structure and flexibility for energy harvesting, the tube liquid–solid triboelectric nanogenerator (TLS-TENG) has attracted much attention. However, it is limited by low output power due to its low surface charge density and transfer efficiency. Researchers in China proposed and constructed TLS-TENG (SVE-TLS-TENG) with enhanced output performance. Through the space volume effect, the open-circuit voltage (Uoc), short-circuit current (Isc), and transfer charge (Qtc) of SVE-TLS-TENG they improved energy harvesting by 3.5 times, 2.3 times, and 2 times, respectively. The SVE-TLS-TENG has high output performance for harvesting low-frequency and high-entropy motion […]

Team develops novel sponge-based triboelectric nanogenerator for corrosion protection in transportation systems
Phys.org September 5, 2023 Researchers in China demonstrated highly elastic, and pressure-resistance sponge fabricated TENG capable of adapting to high strength impact in land and water transportation and scalable for any shape for harvesting wave energy and mechanical energy. The sponge had interconnected network and large size ratio of cavity-wall suitable for contact and separation enabled higher output due to the combination of the electronegativity, adhesion, and antioxidant ability. The operation modes provided options for different operating condition and enabled higher output due to the combination of the electronegativity, excellent adhesion, and antioxidant ability… read more.

A new device can light up 100 LED bulbs with a single drop of water (w/video)
Nanowerk May 10, 2021 The water-droplet/solid-based triboelectric nanogenerator, has so far generated peak power densities of less than one watt per square metre, due to the limitations imposed by interfacial effects. An international team of researchers (China, USA – University of Nebraska, Hong Kong) has developed a droplet-based electricity generator (DEG) using polytetrafluoroethylene (PTFE) film on an indium tin oxide substrate plus an aluminium electrode. When the spreading water connects the two electrodes, all the stored charges on the PTFE can be fully released to generate an electric current. As a result, both the instantaneous power density and energy conversion […]
