We are proposing a collaborative research project with our industrial partner, Ultra Electronics Maritime Systems (UEMS) Inc., Dartmouth, NS, in order to develop micromachined acoustic particle acceleration sensors for sonar applications. Sonobuoys detect sonar signals that are produced or reflected by underwater objects and are extensively used for the detection of submarines. As a major producer of sonobuoys, UEMS has sold millions of these sensitive systems to NATO countries. The piezoelectric hydrophones currently used by UEMS cannot detect the low-frequency sonar signals. **SFU and UEMS teams have collaborated to build the highest performance micromachined accelerometers reported to date. Building upon the success of previous collaborations between SFU and UEMS teams, the goal of this research project is to develop micromachined particle acceleration sensors that can replace hydrophones in sonobuoys. To produce devices with a performance suitable for sonobuoys, we need to significantly improve on the performance the earlier devices while reducing their dimensions. Consequently, this proposal aims to produce novel device designs, microfabrication processes, interface electronics, control algorithms, and packaging technologies to achieve the required performance levels, which are unattainable through simple application of existing methodologies. Three prototypes will be designed, fabricated, tested, and delivered to UEMS over the course of this project. The devices developed through this project will push the limits of performance and lead to generation of new knowledge in the field. **SFU is ideally suited to conduct this research due to existence of team expertise and two cleanrooms. All of the devised designs, prototypes, and future products based on them can be entirely fabricated and assembled in Canada, as needed by the industrial partner. This further provides job opportunities and wealth in Canada. Seven highly qualified personnel will be trained on different aspects of this technology. The training environment created through this proposal will be crucial for the future commercialization of the devices.

我们正在提议与我们的工业合作伙伴 Ultra Electronics Maritime Systems (UEMS) Inc.（位于新斯科舍省达特茅斯）开展一项合作研究项目，以便开发用于声纳应用的微机械声粒子加速度传感器。声纳浮标可探测水下物体产生或反射的声纳信号，广泛用于探测潜艇。作为声纳浮标的主要生产商，UEMS 已向北约国家出售了数百万个此类敏感系统。 UEMS目前使用的压电水听器无法探测低频声纳信号。 **SFU 和 UEMS 团队合作构建了迄今为止报道的最高性能的微机械加速度计。基于 SFU 和 UEMS 团队之前合作的成功，该研究项目的目标是开发微机械粒子加速度传感器，以取代声纳浮标中的水听器。为了生产性能适合声纳浮标的设备，我们需要显着提高早期设备的性能，同时减小其尺寸。因此，该提案旨在产生新颖的器件设计、微加工工艺、接口电子器件、控制算法和封装技术，以达到所需的性能水平，这是通过简单应用现有方法无法实现的。在此项目过程中，将设计、制造、测试并向 UEMS 交付三个原型。通过该项目开发的设备将突破性能极限，并导致该领域新知识的产生。 **SFU 拥有团队专业知识和两个洁净室，非常适合开展这项研究。所有设计、原型和基于它们的未来产品都可以根据工业合作伙伴的需要在加拿大完全制造和组装。这进一步为加拿大提供了就业机会和财富。七名高素质人员将接受该技术不同方面的培训。通过该提案创建的培训环境对于设备未来的商业化至关重要。
