The broader impact/commercial potential of this I-Corps project relates to the emerging "electronics skin" application. Adapting the technology towards early detection of pressure ulcers for at risk individuals with diabetes will result in prevention of amputations for persons with healed diabetic foot ulcers to less than 1%. In particular, a pressure ulcer is a skin injury resulting from prolonged pressure on the skin, often complicated by diabetic's common inability to feel pain due to nerve damage and blood circulation problems reducing the body's ability to heal and increasing risk of infection. Thus, early detection of pressure ulcers is important to prevent worsening conditions that necessitate amputation of limb(s). The technology from this project will result in a low-cost continuous monitoring system that is seamless to one's body and daily activities, enabling improved care for at risk individuals with diabetes.This I-Corps project is based on the technology that combines electrically conductive nanomaterials with a flexible, rubber-like polymer platform in a novel design. The stretchable and flexible electrodes are composed of vertically aligned carbon nanotubes partially embedded in a polydimethylsiloxane substrate, which facilitates reliable and stable devices under both stretching and bending. As a proof-of-concept, the sensor was successfully tested for measuring biological signals of a person. This technology will directly impact the development of sensing and electronic storage devices toward medical and e-skin applications. In particular, the resulting endeavor will directly benefit the medical field, providing greater insight into prognosis and pattern recognition at critical wound development stages.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项目的更广泛的影响/商业潜力与新兴的“电子皮肤”应用有关。 适应该技术的早期检测到患有糖尿病患者的危险患者的压力溃疡，将导致预防糖尿病足溃疡治愈的人的截肢症状，至1％。特别是，压力溃疡是由于对皮肤的长时间压力而导致的皮肤损伤，这通常是由于糖尿病患者的普遍无法使神经损伤和血液循环问题降低人体治愈和增加感染风险的能力而感到疼痛。因此，早期检测到压力溃疡对于防止需要肢体截肢的恶化条件很重要。该项目的技术将导致一个低成本的连续监测系统，该系统无缝地与人体和日常活动无缝，从而改善了患有糖尿病的风险个人的护理。这项I-Corps项目基于该技术，该技术结合了具有灵活的，类似橡胶的聚合物平台的技术。可拉伸和柔性电极由垂直排列的碳纳米管部分组成，部分嵌入了聚二甲基硅氧烷基板中，这有助于在拉伸和弯曲下促进可靠且稳定的设备。作为概念验证，该传感器已成功测试以测量一个人的生物信号。该技术将直接影响传感和电子存储设备对医疗和E-SKIK应用的开发。特别是，由此产生的努力将直接受益于医学领域，在关键伤口发育阶段提供对预后和模式识别阶段的更深入的了解。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智力优点和更广泛的影响来通过评估来支持的。
