Abstract

Abstract: A self-powered technology is a promising approach to achieving sustainable power supply in large-scale wireless sensor networks. Here we report a clock pointer-like triboelectric nanogenerator (CP-TENG) with two non-contact tribo layers which can deliver an abrasion-free operation. The output voltage pulse frequency is tunable by subtly changing the number of electrodes that can improve output power density to some extent. Due to the one-to-one correspondence between voltage pulses and counting points, a self-powered counting and timing systems have been demonstrated via a programmable software platform. Furthermore, by integrating with a wind cup, a self-powered wind speed detector based on the CP-TENG indicates a superior real-time monitoring for wind speed attributed to accurately determining of algorithm parameter. This work not only pushes the development of self-powered systems, but also expands potential applications based on the TENG in intelligent interaction, environmental monitoring, industrial production and meteorological detecting.

The output voltage pulse frequency can be tunable ranged from 3.3 to 40 Hz by changing the number of electrodes. By integrating with a wind cup, a self-powered wind speed detector based on the CP-TENG indicates a superior real-time monitoring for wind speed attributed to accurately determining of algorithm parameter.Image 1 Highlights: A clock pointer-like triboelectric nanogenerator (CP-TENG) was constructed with two non-contact tribo layers which can deliver an abrasion-free operation.
