In northern Alberta, oil sands mining have become one of the major industries that support the Albertan and Canadian economy. Many of the Canadian oil and gas and mining companies like Syncrude Canada would like to extend the lifetime and reduce the maintenance cost of its oil sands mining and transportation equipment and facilities through predicting only structural parts that are prone to failure. Some of the critical equipment used in oil sand exploration are shovel boom, shovel buckets, truck boxes, and truck frames and processing and transportation pipelines. Metal foil strain gauges are currently the standard sensing component used to monitor strain levels on such structures to indicate a critical condition that needs maintenance. Although foil strain gauges have been successfully used for Structural Health Monitoring (SHM), they have disadvantages related to their high cost, high power consumption, and complexity of installation and accessibility; thus, not suitable to be adopted as industrial IoTs for SHM. There is a need for an alternative technique that can address these drawbacks especially providing an easy and quick installation that can withstand the harsh environmental conditions such as dusty environment, moisture, large temperature variation, and severe vibration. The current advancement in micro and Nano-electro mechanical systems (M/NEMS) and semiconductors provides a promising alternative which can integrate a semiconductor strain gauge, circuitry, and wireless module in a small micro-packaged chip for easy installation and connectivity. The objective of this project is to develop a MEMS-based strain sensor that can be deployed for SHM of oil sands mining equipment. It is a collaborative effort between the University of Alberta (UofA) and Syncrude Canada. This phase builds on the success achieved in an earlier collaborative work to build a 3D MEMS-based in-plane strain sensor platform for SSHM of mining and oil and gas equipment in Canada.

在艾伯塔省北部，油砂开采已成为支撑艾伯塔省和加拿大经济的主要产业之一。许多加拿大石油天然气和采矿公司（例如 Syncrude Canada）希望通过仅预测容易发生故障的结构部件来延长其油砂开采和运输设备及设施的使用寿命并降低维护成本。油砂勘探中使用的一些关键设备包括铲斗、铲斗、卡车箱、卡车车架以及加工和运输管道。金属箔应变片目前是标准传感元件，用于监测此类结构上的应变水平，以指示需要维护的关键状况。尽管箔应变片已成功用于结构健康监测（SHM），但它们存在成本高、功耗高、安装和可访问性复杂等缺点；因此，不适合用作健康管理的工业物联网。需要一种能够解决这些缺点的替代技术，特别是提供能够承受恶劣环境条件（例如多尘环境、潮湿、大的温度变化和剧烈振动）的简单且快速的安装。当前微纳机电系统 (M/NEMS) 和半导体的进步提供了一种有前途的替代方案，可以将半导体应变计、电路和无线模块集成在小型微封装芯片中，以便于安装和连接。该项目的目标是开发一种基于 MEMS 的应变传感器，可用于油砂开采设备的 SHM。这是阿尔伯塔大学 (UofA) 和 Syncrude Canada 之间的合作成果。这一阶段建立在早期合作工作所取得的成功之上，为加拿大采矿和石油和天然气设备的 SSHM 构建基于 3D MEMS 的面内应变传感器平台。
