Triboelectric nanogenerators for smart agriculture

Abstract

Rapid iterations of sensing, energy, and communication technologies transform traditional agriculture into standardized, intensive, and smart modern agriculture. However, the energy supply challenge for the plentiful sensors or other microdevices constraints the extensive application of intelligent technologies in agriculture. Triboelectric nanogenerator (TENG), which efficiently converts mechanical energy into electrical energy through contact electrification and electrostatic induction, is considered a promising way to build next-generation intelligent energy supply networks. By efficiently harvesting low-frequency mechanical energy from the agricultural environment, including wind, rain, and water flow energy, TENGs can be a strong contender for distributed power for microdevice networks in smart agriculture. In addition, highly customizable TENGs can be combined with microdevices in agriculture to enable self-powered agricultural monitoring and production strategy adjustment. By deeply exploring the application potential of TENG in agriculture, it is conducive to further promoting unmanned production, refinement, and intelligence of agricultural production and enhancing agriculture's ability to combat natural risks.

Fluid-based triboelectric nanogenerators: unveiling the prolific landscape of renewable energy harvesting and beyond

“…Due to advances in sensor technology, the Internet of Things, and 5G technology, there has been a consistent growth in the need for a wide array of sensors and the customization of energy sources for microdevices within the domain of smart agriculture. 130 TENGs exhibit exceptional efficiency in collecting energy within the micro-nano energy domain. They enable the efficient harnessing of dispersed low-frequency mechanical energy from the environment, encompassing sources such as wind energy, river flows, and rainwater.…”

A Self‐Powered Biochemical Sensor for Intelligent Agriculture Enabled by Signal Enhanced Triboelectric Nanogenerator

“…[13,14] Currently, TENG has achieved the conversion of randomly distributed, low-frequency, irregular water (both raindrop and water-flow energy) and wind energy in the agricultural environment into electrical energy, and for selfpowered sensing, nitrogen fixation, crop growth promotion, air and water purification in smart agriculture. [15][16][17][18] However, due to the relatively high energy consumption of spectrometers or biochemical sensors used for chemical sensing in soil or culture medium, it is currently not possible to rely on the power provided by TENG to achieve self-powered sensing of fertilizer molecules in soil or culture medium. [19,20] Moreover, TENGs can be used as self-powered active biochemical sensors due to their surface characteristics that react to external stimuli.…”
