无线传感器节点和传感器网络的概念在结构健康监测领域得到了广泛的研究。然而，在许多SHM应用中，为传感器、车载处理和遥测组件供电的能力是一个巨大的挑战。为了解决这些问题，人们提出并研究了几种基于压电式和热电式材料的能量采集技术。本文综述了与SHM应用相关的能量收集方面的最新进展和研究问题。我们还提出了一项使用射频(RF)信号向电力传感系统无线传输能量的可行性研究。这项研究的目的是提供一种定期向传感器节点供电的方法，使SHM系统不依赖于车载电源。

The concept of wireless sensor nodes and sensor networks has been widely investigated within the field of structural health monitoring (SHM). However, the ability to power sensors, onboard processing, and telemetry components is a significant challenge in many SHM applications. Several energy harvesting techniques, based on piezoelectric and thermoelectric materials, have been proposed and studied to solve such problems. This article summarizes recent advances and research issues in energy harvesting relevant to SHM applications. We also present a feasibility study for using radio frequency (RF) signals to wirelessly deliver energy to power sensing systems. The goal of this study is to provide a method for supplying power to a sensor node periodically so that the SHM system does not rely on an onboard power source.
