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.

在北方阿尔伯塔，油砂开采已成为支撑阿尔伯塔省和加拿大经济的主要产业之一。许多加拿大石油和天然气以及采矿公司，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和设施的寿命并降低其维护成本。油砂勘探中使用的一些关键设备是铲臂、铲斗、卡车箱和卡车框架以及加工和运输管道。金属箔应变计是目前用于监测此类结构上的应变水平以指示需要维护的临界条件的标准感测组件。虽然箔应变计已成功用于结构健康监测（SHM），但它们具有与高成本，高功耗以及安装和可访问性复杂相关的缺点;因此，不适合用作SHM的工业物联网。需要一种可解决这些缺点的替代技术，特别是提供一种容易且快速的安装，其可承受恶劣的环境条件，例如多尘环境、潮湿、大的温度变化和剧烈的振动。微纳机电系统（M/NEMS）和半导体的当前进步提供了一种有前途的替代方案，其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）和加拿大Syncrude之间的合作努力。该阶段建立在早期合作工作中取得的成功基础上，该合作工作为加拿大采矿和石油天然气设备的SSHM构建了基于3D MEMS的面内应变传感器平台。
