Abstract In this Phase II SBIR project ASTER Labs will enhance a wireless WiFi-based insole that was designed and successfully tested and evaluated during a Phase I trial with elderly persons with dementia and their caregivers, and then investigate its efficacy in reducing caregiver activity and burden, and improving caregiver quality of life. An estimated 5.4 million Americans had Alzheimer's disease in 2016 and a 50% increase in this number is expected by 2030. The majority of these patients (70%) will live at home where they receive 75% of their care from informal, unpaid caregivers, such as family members, friends, and neighbors. These caregivers provide valuable services, often at great economic and psychological cost to themselves. In 2015, over 18 billion hours of unpaid care were estimated to have been provided by over 15 million caregivers. Around 15% of them quit their job or reduced their hours to provide this care. This translated to nearly $222 billion dollars of unpaid care in a single year. In the absence of a cure, dementia patients and caregivers prioritize quality of life as their most valued outcome. Existing commercial solutions to assist caregivers in locating wandering patients lack reliable functionality for indoor environments, require significant infrastructure enhancement, or burden both patient and caregiver with the use of non-discreet electronics packages that must be worn as wristbands or belt mounts. There exists an unmet need to support caregivers by providing a comprehensive localization solution of the patient that works both indoors and outdoors with little to no infrastructure modifications. ASTER Labs' novel device, referred to as Activlink, is a patient localization solution based upon WiFi signal and inertial sensors optimized to assist monitoring by primary and secondary caregivers of dementia patients in building environments. Activlink's purpose is to increase quality of life for caregivers by providing highly accurate indication of a patient's position, combined with real-time alerts of a patient's wandering movements. Caregiver often report reduced abilities to function in normal daily activities due to perpetual safety concerns and the demands of constantly monitoring their patient. Activlink provides on-demand access to real-time location visualization within a building, both while in relatively close proximity to the patient and remotely, for distant family members or secondary caregivers wishing to monitor the patient's location. The innovative concept design for this system provides continuous localization capabilities, so that the quality of life for both patient and caregiver may be enhanced by allowing both to move throughout a home or in large indoor spaces such as a care facility or medical center. This Phase II SBIR will evaluate the efficacy of the WiFi-based Activlink insole to provide caregivers with augmented patient awareness, aiming to immediately improve their quality of life by reducing their direct burden of continuous in care person oversight. Embedded randomized controlled evaluations will be completed using semi-structured interviews and observation data collected on 176 persons with moderate dementia, their family caregivers, and professional care providers.

摘要 在第二阶段SBIR项目中，ASTER实验室将增强一种基于无线WiFi的鞋垫， 在I期试验期间成功地对患有痴呆症的老年人及其 照顾者，然后调查其在减少照顾者活动和负担， 生活质量据估计，2016年有540万美国人患有阿尔茨海默病， 预计到2030年将达到这一数字。这些患者中的大多数（70%）将住在家里，他们接受75%的 他们从非正式的、无偿的照顾者那里得到照顾，如家庭成员、朋友和邻居。这些照顾者 提供有价值的服务，往往要付出巨大的经济和心理代价。2015年，超过18 据估计，超过1 500万名护理人员提供了10亿小时的无酬护理。15%左右 他们中的一些人辞职或减少工作时间来提供这种护理。这相当于近2220亿美元的 一年的无薪护理。在没有治愈方法的情况下，痴呆症患者和护理人员优先考虑生活质量 作为他们最有价值的成果。现有的商业解决方案，以帮助护理人员找到流浪病人 缺乏室内环境的可靠功能，需要显著的基础设施增强，或负担 患者和护理人员都使用必须作为腕带佩戴的非谨慎电子包 或皮带安装件。存在通过提供全面的本地化来支持护理人员的未满足需求 在室内和室外工作的患者的解决方案，很少或没有基础设施的修改。Aster 实验室的新设备，被称为Activlink，是一种基于WiFi信号和惯性的患者定位解决方案。 优化传感器以帮助建筑物中痴呆患者的主要和次要护理者进行监测 环境. Activlink的目的是通过提供高度准确的 患者位置的指示，结合患者徘徊运动的实时警报。护理者 由于长期的安全问题，经常报告在正常日常活动中的功能能力降低， 要求他们不断地监控病人。Activlink提供对实时位置的按需访问 在建筑物内的可视化，无论是在相对接近患者的同时，还是在远程，对于远程 希望监测患者位置的家庭成员或二级护理人员。创新理念 该系统的设计提供了连续的定位能力，因此患者的生活质量 和护理人员的能力可以通过允许他们在整个家庭或大的室内空间中移动来增强， 作为一个护理机构或医疗中心。本阶段II SBIR将评估基于WiFi的Activlink的有效性 鞋垫，为护理人员提供增强的病人意识，旨在立即提高他们的质量， 生活，减少他们的直接负担，不断在照顾人的监督。嵌入式随机对照 将利用半结构化访谈和对176人收集的观察数据完成评价 中度痴呆患者、他们的家庭照顾者和专业护理提供者。
