The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project is to improve on-demand, low-cost blood pressure monitoring. High blood pressure (BP) is a major cardiovascular risk factor affecting up to 1 billion people worldwide. It is treatable, yet hypertension awareness and control is not common. Ubiquitous BP monitoring could improve hypertension management but existing devices require an inflatable cuff and are inconvenient for on-demand BP measurement. The market for a portable, cuff-less blood pressure monitor is estimated in the tens of billions of dollars. This project will develop a technology for portable, convenient BP monitoring. The proposed project will advance a novel technology for blood pressure monitoring. The proposed device uses the standard oscillometric finger-pressing method, but instead of using an inflated cuff, the user presses a finger against a sensor to determine the blood pressure. This program will advance the hardware, algorithm, and associated app. The R&D plan includes optimizing the sensing technology to accommodate a wide range of finger sizes; miniaturization of the hardware; optimization of the algorithm for a broad range of low, normotensive and hypertensive users; and development of the app user interface.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项小型企业创新研究（SBIR）II期项目的更广泛的影响/商业潜力是改善按需，低成本的血压监测。高血压（BP）是影响全球多达10亿人的主要心血管危险因素。它是可以治疗的，但是高血压意识和控制并不常见。无处不在的BP监测可以改善高血压管理，但现有设备需要充气袖口，并且对按需BP测量是不方便的。据估计，估计便携式，无袖口的血压监测器的市场。该项目将开发一种用于便携式，方便的BP监视的技术。拟议的项目将推进血压监测的新技术。所提出的设备使用标准的振荡指定方法，但用户不使用夸张的袖口，而是将手指压在传感器上以确定血压。该程序将推进硬件，算法和关联的应用程序。 研发计划包括优化传感技术，以适应各种手指尺寸；硬件的小型化；对算法的优化，用于广泛的低，正常和高血压的使用者；该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响评论标准通过评估来支持的。
