 This research has developed a novel type of piezoelectric nanogenerator, PENG, that can be used for practical applications. The PENG is constructed with a combination of materials including CSPBBR3, T3C2TX, and PVDF. The material combination allows for the efficient transfer of polarized charges from the T3C2TX nano sheets to the electrodes, resulting in increased output voltage. Additionally, the PENG is designed to be self-polarizing, meaning it does not require external stimuli to generate power. This makes the device more efficient and reliable. The PENG was tested in practice and found to be able to produce enough voltage to light up 150 LEDs in an electronic watch. Furthermore, the PENG was shown to have good water and thermal stability due to its protective layer of PVDF. This article was authored by Yousueh, Tao Yang, Yapeng Jing, and others.
