CAREER: Wearable Accelerometers for Continuous Respiratory Sound Monitoring

这项研究的目的是开发高灵敏度的轻量级加速度计，可以像绷带或背心一样佩戴在身体上，用于连续的呼吸声监测。该方法基于一种新颖的气隙悬臂梁结构，将加速度计的灵敏度提高了几个数量级，并采用了独特的智能纺织技术，使封装的加速度计重量轻、可穿戴。这项拟议的研究可能会导致呼吸声音监测的范式转变，并推动各种可穿戴健康监测传感器的开发。提出的新型气隙悬臂梁结构可以实现高性能和低成本的加速度计，这些加速度计在许多工业、科学、民用和军事应用中都是非常理想的。拟议系统的成功开发将对各种临床和医疗应用产生重大影响，如手术室的麻醉监测、哮喘管理、飞行员和其他军事人员的非侵入性生命体征监测、重症监护病房的患者监测、护理设施和紧急医疗服务等。预计将产生重大的社会和经济影响。与这项研究相关的令人兴奋的新方法和发现将首先被纳入PI正在教授的一门微型/纳米机电系统课程中。然后，将开发一门关于可穿戴生理传感器的新课程。最终，将开发出一个独特的可穿戴健康监测研究生教育项目。本科生和高中生都将参与拟议的研究工作。通过利用韦恩州立大学的地理位置，国际和平协会致力于扩大代表性不足群体的参与。

The objective of this research is to develop high-sensitive light-weight accelerometers that can be body-worn like a bandage or vest for continuous respiratory sound monitoring. The approach is based on a novel air-spaced cantilever structure to increase the accelerometer sensitivity by orders of magnitude and a unique intelligent textile technology to make the packaged accelerometer light-weight and wearable. The proposed research may lead to a paradigm shift in the monitoring of respiratory sounds and advance the development of various wearable health monitoring sensors. The novel air-spaced cantilever structures proposed may enable high-performance and low-cost accelerometers that are highly desirable for many industrial, scientific, civilian and military applications. The successful development of the proposed system will have significant impacts on various clinical and healthcare applications such as anesthesia monitoring in operating rooms, asthma management, non-invasive vital sign monitoring for pilots and other military personnel, patient monitoring in intensive care units, nursing facilities, and emergency medical services, etc. Significant societal and economic impacts are expected. The exciting new methods and findings associated with the research will be first incorporated into a Micro/Nano Electro Mechanical Systems course the PI is teaching. Then a new course on wearable physiological sensors will be developed. Eventually, a unique graduate level education program on wearable health monitoring will be developed. Both undergraduate and high school students will be involved in the proposed research work. By taking advantage of the geographic location of Wayne State University, the PI is committed to broaden the participation of underrepresented groups.
