项目摘要

In the last decade, energy harvesting has been an exploding research field in the worldwide by promising of self-powered systems, including wireless sensor networks. The last few years have seen the emergency of several dedicated world class research groups, dedicated international conferences, heavily investments by government research funding bodies, including the UK, and industrial stakeholders. Nevertheless, several critical roadblocks remain that have so far prevented the technology from practical applications. For example, currently, most vibration-based energy harvesters are designed to work at or near resonance frequency. Unfortunately, in the most majority of practical scenarios, ambient vibration is well below the resonant frequency and frequency-varying or totally random over a wide range frequency. The energy harvested reduces significantly outside the resonant frequency. The resolution of these presents scientific challenges, requiring highly innovative solutions.This EPSRC funded PhD studentship will address this challenge by researching into broadband vibration energy harvesting for low frequencies via a number of innovative approaches, such as frequency-up conversion and novel energy harvester designs. The research outcome of the project will be able for industry to use the developed novel energy harvester for self-powered systems, such as structural health monitoring applications.

在过去的十年里，能量收集已经成为一个爆炸性的研究领域，在世界范围内，有希望的自供电系统，包括无线传感器网络。过去几年，我们看到了几个专门的世界级研究小组、专门的国际会议、政府研究资助机构（包括英国）和工业利益相关者的大量投资。然而，目前仍有几个关键的障碍阻碍了这项技术的实际应用。例如，目前，大多数基于振动的能量采集器被设计为工作在或接近共振频率。不幸的是，在大多数实际情况下，环境振动远低于谐振频率，并且在很宽的频率范围内频率变化或完全随机。所收集的能量在谐振频率之外显著减少。这些问题的解决提出了科学挑战，需要高度创新的解决方案。EPSRC资助的博士研究生将通过一系列创新方法研究低频宽带振动能量收集，如频率上升转换和新型能量收集器设计，来解决这一挑战。该项目的研究成果将能够为工业使用开发的新型能量采集器用于自供电系统，例如结构健康监测应用。
