Fibos Inc. is a small Canadian company aiming to disrupt the industrial sensing industry by replacing conventional electrical sensors with all-optical ones. Their optical fibre strain sensor is inherently safe, eliminating risks of explosion in hazardous environments that improve safety for workers and equipment. However, the company is facing significant barriers to manufacture fibre optical sensors that can be robust and cost effective for the high temperature and pressure environments as required in sensing rotor assemblies in turbines. Assembly and packaging of the current materials is failing at the high temperature and pressure limits of existing and potential new customers. This Engage project addresses the key requirement by proposing an "all-glass" solution of the key sensing fixture, thereby eliminating all of the lower temperature and lower strength materials. The approach aims for a simple, all-in-one manufacturing procedure to fabricate and package optical fiber gratings into robust optical sensing transducers. The University of Toronto team will apply ultrafast lasers to exploit their expertise in 'three-dimensional' nano-manufacturing to embed high finesse optical devices inside of thin glass fibres, while facilitating glass-to-glass micro-welding for the first time to robust transducers. There are substantial benefits to Canada if this project is successful: (1) academic leadership in 3D manufacturing of unique optical sensors; (2) generation of intellectual property; (3) new manufacturing processes and product concepts; (4) training of R&D personnel with unique skills and knowhow for translation from a university to a Canadian industrial environment; and (5) long-term job creation for manufacturing, sales and R&D personnel.

菲博斯公司是一家加拿大小公司，旨在通过用全光学传感器取代传统的电传感器来颠覆工业传感行业。 他们的光纤应变传感器具有固有的安全性，消除了危险环境中的爆炸风险，提高了工人和设备的安全性。 然而，该公司在制造光纤传感器方面面临着重大障碍，这些传感器可以在高温和高压环境中具有鲁棒性和成本效益，如传感涡轮机转子组件所需。 现有材料的组装和包装在现有和潜在新客户的高温和高压极限下失败。 该Engage项目通过提出关键传感夹具的“全玻璃”解决方案来满足关键要求，从而消除了所有温度较低和强度较低的材料。 该方法的目的是一个简单的，所有在一个制造过程中制造和封装光纤光栅到强大的光学传感器。多伦多大学的团队将应用超快激光器，利用他们在“三维”纳米制造方面的专业知识，将高精细度光学器件嵌入薄玻璃纤维中，同时首次促进玻璃与玻璃之间的微焊接，以实现坚固的传感器。 如果该项目取得成功，将给加拿大带来重大利益：（1）在独特光学传感器的三维制造方面的学术领导地位;（2）产生知识产权;（3）新的制造工艺和产品概念;（4）培训具有独特技能和专门知识的研发人员，以便从大学转化为加拿大的工业环境;以及（5）为制造、销售和研发人员创造长期就业机会。
