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 energy, and its output displacement current could serve as a compact signal generator for underwater wireless communication. According to the researchers their work provides new insight for the design and large-scale application of LS-TENG… read more. TECHNICAL ARTICLEÂ
