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.

小型企业创新研究(SBIR)第二阶段项目的更广泛影响/商业潜力是改进按需、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风险因素。它是可以治疗的，但高血压的意识和控制并不常见。无处不在的血压监测可以改善高血压的管理，但现有的设备需要充气袖带，不方便按需测量血压。据估计，便携式无袖带血压计的市场价值高达数百亿美元。该项目将开发一种便携、方便的血压监测技术。拟议中的项目将推进一种新的血压监测技术。建议的设备使用标准的示波法手指按压，但用户不使用充气袖带，而是将手指按在传感器上来确定血压。该计划将推进硬件、算法和相关应用程序的发展。研发计划包括优化传感技术以适应各种手指尺寸；硬件小型化；为广泛的低血压、正常血压和高血压用户优化算法；以及开发APP用户界面。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
