The broader impact/commercial potential of this I-Corps project will be to improve the health and performance of sports, industrial, or military athletes on a court, in a warehouse, or serving our country, through a wearable liquid metal sensor solution. One of the largest over-use injuries that is prevalent in non-contact injuries, occurs at the foot and ankle, resulting in millions of dollars lost each year through missed time off and rehabilitation costs. Therefore, this wearable solution is designed to assess current movement patterns and function as a pre-rehabilitation device, which provides an assessment to warn wearers and practitioners of potential over-use movement patterns. In addition, the wearable can be used as a training device to ensure proper rehabilitation techniques and "back to work or play" range of motion assessments, ensuring effective decision making about when the wearer can and should return to activity. Based on wearable liquid metal technology, this device can be applied to all other joints in the human body, creating a wide range of uses which broaden our potential customer base beyond sports pre-rehabilitation of the ankle. This I-Corps project takes the precision of research equipment out of the laboratory and into the environment where training actually occurs. The wearable device designed for this project is comprised of soft liquid metal sensors and a machine-learning computational platform that is both unrestrictive and non-obtrusive around the wearer's feet and ankles. Through pilot testing utilizing the gold standard of an optical motion capture system, specific sensor positions have been identified that provide linear relationships to the angular changes in single and tri-planar movement(s) of the ankle complex. Paired with wireless communication capabilities, the wearable device will allow managers, coaches, and other practitioners of human performance the opportunity to detect asymmetrical leg movement patterns that cause muscular imbalances and often lead to non-contact injuries. Through user experience (UX) testing protocols, software development will enable customizable user interfaces and reports that answers the "voice of the customer", looking for data from the ground up. Based on the results from laboratory testing, the next step is to field test the wearable device and synchronize data visualizations with appropriate mobile devices in order to gain deeper insight on customer wants and needs.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.

I-Corps项目更广泛的影响/商业潜力将是通过可穿戴液态金属传感器解决方案，改善体育、工业或军事运动员在球场、仓库或为国家服务时的健康和表现。在非接触性伤害中，最大的过度使用伤害之一发生在足部和脚踝，每年因错过休假和康复费用而损失数百万美元。因此，这种可穿戴解决方案旨在评估当前的运动模式，并作为一种预康复设备，提供评估，警告佩戴者和从业者潜在的过度使用的运动模式。此外，可穿戴设备还可以用作训练设备，以确保适当的康复技术和“重返工作或娱乐”的运动范围评估，确保有效地决定佩戴者何时可以和应该重返活动。基于可穿戴液态金属技术，该设备可以应用于人体的所有其他关节，创造了广泛的用途，扩大了我们的潜在客户群，超出了踝关节的运动预康复。这个I-Corps项目将精确的研究设备带出了实验室，进入了实际训练的环境。为该项目设计的可穿戴设备由软液态金属传感器和机器学习计算平台组成，该平台在穿戴者的脚和脚踝周围既不受限制又不引人注目。通过利用光学运动捕捉系统的黄金标准进行先导测试，已经确定了特定的传感器位置，这些位置提供了与踝关节复合体的单平面和三平面运动的角度变化的线性关系。配合无线通信功能，可穿戴设备将允许管理人员、教练和其他人类表演从业者有机会检测不对称的腿部运动模式，这些运动模式会导致肌肉失衡，并经常导致非接触性损伤。通过用户体验（UX）测试协议，软件开发将启用可定制的用户界面和报告，以回答“客户的声音”，从头开始寻找数据。基于实验室测试的结果，下一步是对可穿戴设备进行现场测试，并与适当的移动设备同步数据可视化，以便更深入地了解客户的需求。该奖项反映了美国国家科学基金会的法定使命，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。
