Abstract

Current sensors used for river monitoring, especially devices targeting low-flow rivers, still face challenges such as high costs, difficulties in supplying power, and limited measurement ranges. This study describes a Bionic self-powered wireless sensor device based on triboelectric nanogenerator. This economical method successfully overcomes the drawbacks of traditional sensors by combining a triboelectric nanogenerator with a turbine inspired by fish biology. At 0.5 m/s flow velocity, the bio-inspired turbine exhibits 56.1 % more instantaneous torque than hybrid turbines, allowing for precise low-flow monitoring (0.1–3 m/s range) with 0.995 R2. Its simplified design and small 50 mm TENG component save production costs while preserving measuring accuracy. In order to provide thorough environmental monitoring, the system also includes integrated temperature and humidity sensors and solar panels for self-powering. This invention, which combines bionic engineering and triboelectric nanogenerator technology, offers an environmentally beneficial way to manage water resources, especially in low-velocity settings where conventional sensors function poorly. Energy harvesting and flow sensing are accomplished simultaneously by the integrated design, which is a helpful development in environmental monitoring infrastructure.

基于摩擦电纳米发电机的河流生态监测仿生自供电无线传感器装置

目前用于河流监测的传感器，特别是针对低流量河流的设备，仍然面临着诸如成本高、供电困难和测量范围有限等挑战。研究了一种基于摩擦电纳米发电机的仿生自供电无线传感器装置。这种经济的方法通过将摩擦纳米发电机与受鱼类生物学启发的涡轮机结合起来，成功地克服了传统传感器的缺点。在0.5 米/秒的流速下，仿生涡轮机比混合动力涡轮机多出56.1% %的瞬时扭矩，允许精确的低流量监测（0.1 - 米/秒范围），R2为0.995。其简化的设计和小型50 mm TENG组件节省了生产成本，同时保持了测量精度。为了提供全面的环境监测，该系统还包括集成的温度和湿度传感器以及用于自供电的太阳能电池板。这项发明结合了仿生工程和摩擦电纳米发电机技术，提供了一种对环境有益的水资源管理方法，特别是在低速环境中，传统传感器的功能很差。通过一体化设计，能量收集和流量传感同时完成，这是环境监测基础设施的有益发展。

期刊介绍： Sensors and Actuators A: Physical brings together multidisciplinary interests in one journal entirely devoted to disseminating information on all aspects of research and development of solid-state devices for transducing physical signals. Sensors and Actuators A: Physical regularly publishes original papers, letters to the Editors and from time to time invited review articles within the following device areas: • Fundamentals and Physics, such as: classification of effects, physical effects, measurement theory, modelling of sensors, measurement standards, measurement errors, units and constants, time and frequency measurement. Modeling papers should bring new modeling techniques to the field and be supported by experimental results. • Materials and their Processing, such as: piezoelectric materials, polymers, metal oxides, III-V and II-VI semiconductors, thick and thin films, optical glass fibres, amorphous, polycrystalline and monocrystalline silicon. • Optoelectronic sensors, such as: photovoltaic diodes, photoconductors, photodiodes, phototransistors, positron-sensitive photodetectors, optoisolators, photodiode arrays, charge-coupled devices, light-emitting diodes, injection lasers and liquid-crystal displays. • Mechanical sensors, such as: metallic, thin-film and semiconductor strain gauges, diffused silicon pressure sensors, silicon accelerometers, solid-state displacement transducers, piezo junction devices, piezoelectric field-effect transducers (PiFETs), tunnel-diode strain sensors, surface acoustic wave devices, silicon micromechanical switches, solid-state flow meters and electronic flow controllers.
