New Technology – The importance of new innovative technologies will aid in energy solutions. News from a group of inventors establishing the “Triboelectric nanogenerator harvests wind energy” is set to capture wind energy to produce long-term power solutions.
Nano Werk announced the “researchers at Georgia Tech and the Beijing Institute of Nanoenergy and Nanosystems, led by Xiaonan Wen and Zhong Lin Wang, report a triboelectric effect based wind energy harvester as a sustainable power source and a self-powered wind vector sensor system for wind speed and direction detection (“Triboelectric Nanogenerator for Harvesting Wind Energy and as Self-Powered Wind Vector Sensor System“).
“The nanogenerator consists of an fluorinated ethylene propylene (FEP) film and two aluminum foils connected with a ground through an external load. Its mechanism is based on the charge transfer between the aluminum electrode and the ground by utilizing the wind-induced vibration of the FEP film between the two aluminum electrodes. Moreover, the nanogenerators have been utilized to design a self-powered wind vector sensor system for detecting the wind speed and direction.”
“The integrated triboelectric nanogenerator produces an output voltage up to 100 V, an output current of 1.6 µA, and an output power of 0.16mW under a load of 100 MΩ, which can be used to light up tens of commercial LEDs.”
New solutions in energy innovation will derive from academia. The work of global collaboration can deliver energy efficiency and optimization of power. It is necessary to harvest mind and power to bridge intelligence for sustainable solutions and smart grid efficiency.
