DESCRIPTION (provided by applicant): Despite the growing market demand for a consumer-friendly energy balance monitor, there are no commercially available solutions satisfying consumer needs. Valencell's long-term goal is to provide a seamless, wearable platform for health and fitness monitoring that is autonomous, user-friendly, comfortable for daily use, accurate in multiple life activities, and able to provide actionable feedback to the user. This preventive healthcare platform will provide end users, their doctors, and their trainers with easy-to-use, actionable feedback promoting a healthy lifestyle. Valencell has previously developed and alpha-tested the Healthset(R), an autonomous wearable health and fitness monitor that measures vital signs and physical activity and presents this information graphically on a smartphone. While the Healthset(R) measures physical activity of various intensity levels, it does not contain algorithms for processing energy expenditure assessments from raw physical activity data. Experimental evidence suggests that Valencell's Healthset(R) algorithms can be augmented to provide accurate energy expenditure assessments for daily life activities, suitable for clinical, academic, and consumer applications. Thus, the specific goal of this Phase I feasibility study is to validate the Healthset(R) as a seamless energy expenditure monitoring tool. In this NIH Phase I program, Valencell and collaborators at the Duke University will: 1.) fabricate pre-designed Healthset units optimized for measuring energy expenditure, 2.) collect time-correlated Healthset(R) data in a 10-person indirect calorimetry study, 3.) generate statistical models for energy expenditure, and 4.) validate these models in a second clinical study. This Phase I program will deliver the preliminary performance specifications for the Healthset(R) energy expenditure monitor used in multiple physical activities. The opportunity for assessing calories consumed will also be addressed in the final report for a complete energy balance monitoring platform. PUBLIC HEALTH RELEVANCE: Modifiable health risk factors such as high stress, poor diet, and a sedentary lifestyle account for 25% of all medical expenses and millions of deaths per year worldwide. Seamless, accurate, real-time feedback on personal health and fitness can empower individuals to live healthier lives, saving trillions in medical expenses. The energy balance monitoring technology proposed in this Phase 1 SBIR would make healthy living easier, more effective, and more affordable.

描述（由申请人提供）：尽管对消费者友好的能量平衡监测器的市场需求不断增长，但没有满足消费者需求的市售解决方案。Valencell的长期目标是为健康和健身监测提供一个无缝的可穿戴平台，该平台是自主的，用户友好的，日常使用舒适，在多种生活活动中准确，并能够为用户提供可操作的反馈。这个预防性医疗保健平台将为最终用户，他们的医生和他们的培训师提供易于使用，可操作的反馈，促进健康的生活方式。Valencell之前已经开发并测试了Healthset（R），这是一种自主可穿戴健康和健身监测器，可以测量生命体征和身体活动，并在智能手机上以图形方式显示这些信息。虽然Healthset（R）测量各种强度水平的身体活动，但它不包含用于处理原始身体活动数据的能量消耗评估的算法。实验证据表明，Valencell的Healthset（R）算法可以被增强，以提供针对日常生活活动的准确能量消耗评估，适用于临床、学术和消费者应用。因此，第一阶段可行性研究的具体目标是验证Healthset（R）作为一种无缝的能量消耗监测工具。在这个NIH第一阶段计划中，Valencell和杜克大学的合作者将：1。制造预先设计的Healthset单元，优化用于测量能量消耗，2.）在10人间接测热研究中收集时间相关的Healthset（R）数据，3.）生成能量消耗的统计模型，以及4.）在第二次临床研究中验证这些模型。该第一阶段计划将提供用于多种体力活动的Healthset（R）能量消耗监测器的初步性能规格。评估卡路里消耗的机会也将在完整的能量平衡监测平台的最终报告中讨论。公共卫生关系：可改变的健康风险因素，如高压力、不良饮食和久坐不动的生活方式，占全球所有医疗费用的25%，每年有数百万人死亡。关于个人健康和健身的无缝、准确、实时反馈可以使个人过上更健康的生活，节省数万亿美元的医疗费用。在第一阶段SBIR中提出的能量平衡监测技术将使健康生活更容易，更有效，更实惠。
