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. image
