A Multifunctional Hydrogel with Multimodal Self-Powered Sensing Capability and Stable Direct Current Output for Outdoor Plant Monitoring Systems

Nano-Micro Letters, Год журнала: 2024, Номер 17(1)

Опубликована: Ноя. 27, 2024

Smart farming with outdoor monitoring systems is critical to address food shortages and sustainability challenges. These facilitate informed decisions that enhance efficiency in broader environmental management. Existing equipped energy harvesters self-powered sensors often struggle fluctuating sources, low durability under harsh conditions, non-transparent or non-biocompatible materials, complex structures. Herein, a multifunctional hydrogel developed, which can fulfill all the above requirements build self-sustainable solely by it. It serve as stable harvester continuously generates direct current output an average power density of 1.9 W m

An Adaptive Grid Generation Approach to Pipeline Leakage Rapid Localization Based on Time Reversal

Sensors, Год журнала: 2025, Номер 25(6), С. 1753 - 1753

Gas pipeline leakage will result in casualties and property losses if not detected time. Conventional localization methods usually rely on dense grid distribution, leading to high computational costs. This study proposes a time-reversal-based adaptive generation approach enhance efficiency localization. The method introduces resolution adjustment parameter optimize captured signals, allowing for concentration areas based energy distribution. Based this principle, three steps—including signal computation, conventional TR computation the grids—are introduced. Then, an experimental is conducted 55.8 m PVC with piezoceramic transducers, capturing negative pressure wave signals from four points. results demonstrate that proposed maintains comparable accuracy while reducing number of grids time only 0.6% 2.4% those required by uniform methods, respectively. findings offers computationally efficient accurate solution real-time monitoring.
