The broader impact/commercial potential of this I-Corps project is to develop a wireless, skin-like vital signs monitor that provides clinical grade data while maximizing patient comfort and mobility. The current clinical standard for monitoring patient vital signs consists of physically tethering the patient to multiple sensors with wires connected to a bed-side monitor. These systems present a number of drawbacks for those involved in the care stream, including patients, providers, and payers. The current wired systems are not typically used for detailed monitoring at home. They are a barrier to patient mobility and lead to skin irritation and infection. The value proposition of this project is to improve quality of care and shorten hospital stays by permitting uninhibited patient mobility and preventing skin injury while providing critical data to accurately diagnose patients. Additionally, the development of a wireless system will enable flexibility in monitoring equipment for hospitals and has significant potential to improve care in low-resource or at-home settings.This I-Corps project will further develop a flexible, stretchable wireless sensor platform which can improve monitoring of patient vital signs in a wide array of potential healthcare applications. The sensor consists of an ultrathin nanomembrane electrode supported by a soft flexible substrate. The flexible, stretchable nature of the sensor enables conformal contact with a patient's skin and high-resolution measurement of multiple vital signs to monitor heart, brain, and muscle activity. These wireless measurements can be used to monitor patients in hospital or at-home settings. Combining multiple high-resolution signal modalities will improve diagnostic accuracy as machine learning methods are implemented.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.

该I-Corps项目的更广泛影响/商业潜力是开发一种无线皮肤样生命体征监测仪，可提供临床等级数据，同时最大限度地提高患者舒适度和移动性。用于监测患者生命体征的当前临床标准包括用连接到床边监测器的电线将患者物理地拴系到多个传感器。这些系统对于参与护理流的那些人（包括患者、提供者和支付者）呈现出许多缺点。目前的有线系统通常不用于家庭的详细监控。它们是患者活动的障碍，并导致皮肤刺激和感染。该项目的价值主张是通过允许患者自由移动和防止皮肤损伤，同时提供关键数据以准确诊断患者，从而提高护理质量并缩短住院时间。此外，无线系统的开发将使医院监测设备具有灵活性，并具有改善低资源或家庭环境中的护理的巨大潜力。该I-Corps项目将进一步开发一个灵活的、可伸缩的无线传感器平台，该平台可以在广泛的潜在医疗保健应用中改善对患者生命体征的监测。该传感器由一个由柔软的柔性基底支撑的纳米膜电极组成。该传感器的柔性、可拉伸性质使其能够与患者皮肤进行适形接触，并对多个生命体征进行高分辨率测量，以监测心脏、大脑和肌肉活动。这些无线测量可用于在医院或家庭环境中监测患者。 该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
