Triboelectric nanogenerators as flexible power sources

Nanowire Piezoelectric Nanogenerators on Plastic Substrates as Flexible Power Sources for Nanodevices

Research applications in biomedical science and technology usually require various portable, wearable, easy-to-use, and/or implantable devices that can interface with biological systems. Organic or hybrid organic–inorganic microelectronics and nanoelectronics have long been a possibility. However, these devices require a power source, such as electrochemical cells or piezoelectric, thermoelectr...

Theoretical study of contact-mode triboelectric nanogenerators as an effective power source†

A theoretical model for contact-mode TENGs was constructed in this paper. Based on the theoretical model, its real-time output characteristics and the relationship between the optimum resistance and TENG parameters were derived. The theory presented here is the first in-depth interpretation of the contact-mode TENG, which can serve as important guidance for rational design of the TENG structure...

Theory of sliding-mode triboelectric nanogenerators.

The triboelectric nanogenerator (TENG) is a powerful approach toward new energy technology, especially for portable electronics. A theoretical model for the sliding-mode TENG is presented in this work. The finite element method was utilized to characterize the distributions of electric potential, electric field, and charges on the metal electrodes of the TENG. Based on the FEM calculation, the ...
