SBIR Phase I: Wearable System for Stress Management via Real Time Stress Tracking and Biofeedback

这个小企业创新研究（SBIR）第一阶段项目的更广泛的影响/商业潜力正在为警察和其他预计在高压力下履行工作职责的服务人员创造一个工具。 这个第一阶段项目旨在开发一种技术，该技术通过可穿戴传感器单元创建压力评分，并在用户处于“红色区域”时发出警报，以便根据生理监测做出决策。这项技术的最初目标市场是约10亿美元的执法市场，因为人们非常需要能够帮助缓和局势并可能改善使用武力决策的工具。急性压力影响决策的痛点在军事和专业运动市场也得到了验证。这个小型企业创新研究（SBIR）第一阶段项目旨在开发一种可穿戴技术，利用皮肤电导率测量压力，并通过振动反馈提醒用户。第一阶段项目建议：（1）对警察进行试点研究，以在场景训练期间收集皮肤电导数据，（2）使用这些数据构建机器学习人工智能（AI）模型，该模型具有对不良决策的高预测准确性，（3）确定理想的传感器位置并构建定制的可穿戴表带附件，（4）开发移动的应用程序，为人员和培训人员建立数据可视化界面，以及（5）使用原型测试人员在决策过程中提供振动反馈的有效性。第一阶段的成功结束可能会导致一个硬件-软件原型，使用皮肤电导信号测量警察的情绪压力，然后通过振动反馈提醒用户，当他们处于高度压力水平时。这个奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is creating a tool for police officers and other service members who are expected to perform their job duties under high stress. This Phase 1 project seeks to develop a technology that creates stress scores and alerts users when they are in “red zones” for decision making based on physiological monitoring via a wearable sensor unit. The initial target market segment for this technology is the ~$1 billion law enforcement market as there is a high need for tools that can help de-escalate situations and potentially improve the use-of-force decisions. The pain points of acute stress impacting decision-making have been validated in military and professional athletic markets as well.This Small Business Innovation Research (SBIR) Phase I project aims to develop a wearable technology that uses skin conductivity to measure stress and alert users via vibrational feedback. This Phase 1 project proposes to: (1) run a pilot study on police officers to collect skin conductance data during scenario training, (2) build machine learning artificial intelligence (AI) models with a high predictive accuracy of poor decision making using this data, (3) determine ideal sensor location and build a custom wearable strap attachment, (4) develop the mobile application to build a data visualization interface for officers and trainers, and (5) test the effectiveness of delivering vibrational feedback during decision making of officers using the prototype. The successful conclusion of Phase 1 may lead to a hardware-software prototype that measures the police officers' emotional stress using a skin conductance signal, then alerts the user via vibrational feedback when they are in a heightened level of stress.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.
