Collecting data from a sensor enclosed in a metallic structure while being a challenging task, is greatly desirable in many industrial applications including condition monitoring and wireless sensing. Conventional communication schemes fail to establish a secure communication in order to transmit data to and from sensors that are enclosed in sealed metallic containers or those that are isolated from the operator (reader) through a thick metal layer. The challenge is further exacerbated if power needs to be transmitted to data generation unit (sensor) through the metallic barrier. This research aims at developing a robust technology for a robotic drone to enable continuous monitoring of sensors (e.g., gas, fluid level, surface, etc.) in hazardous enclosed environments. Specifically, the objective of this project is to design, develop and evaluate a robust piezo-based system to transfer low-to-medium data rate signals through metal barriers.**

在许多工业应用中，包括条件监测和无线传感，从金属结构中封闭的传感器收集数据是非常需要的。传统的通信方案未能建立安全的通信，以至于将数据传输到密封的金属容器或与操作员（读取器）通过厚的金属层中隔离的传感器传输。如果需要通过金属屏障将功率传输到数据生成单元（传感器），则挑战将进一步加剧。这项研究旨在为机器人无人机开发强大的技术，以在危险的封闭环境中连续监测传感器（例如气体，流体水平，表面等）。具体而言，该项目的目的是设计，开发和评估一个基于压电的系统，以通过金属屏障传输低到中等的数据速率信号。**
