Self-powered Autonomous Device for WIreless struCtural Health monitoring (SANDWICH)

该项目将开发新的和优化现有的功率采集器技术，并通过有效的功率管理将其集成，以实现足够的能量水平，为飞机结构的轻型自主健康监测系统提供动力。利用从环境中收集的能量为可以无线通信的传感器网络供电，该系统将检测损坏并确定飞机部件的结构完整性。安全性和可靠性对航空航天工业至关重要。该项目将在这些领域取得重大飞跃，促进对地面和飞行中的飞机进行连续检查。现有的检查技术依赖于使飞机退役。这种停机时间是昂贵的和周期性的。SHM系统提供的连续覆盖将能够在早期实时识别故障，缩短停机时间，并促进更安全，更有效的维护计划。

This project will develop new and optimise existing power harvester technologies and integrate them through efficient power management to achieve sufficient levels of energy to power a lightweight autonomous health monitoring system for aircraft structures. Using energy scavenged from the environment to power a network of sensors which can communicate wirelessly, the system will detect damage and determine the structural integrity of aircraft components. Safety and reliability are critical to the aerospace industry. This project will make a major leap forward in these areas, by facilit-ating continuous inspection coverage for aircraft both on the ground and in flight. Existing inspection techniques, rely on taking an aircraft out of service. This downtime is costly and periodic. Continuous coverage offered by a SHM system will be able to identify failures at an early stage in realtime, reducing the length of downtime, and facilitating safer and more effective maintenance schedules.
