The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase II project will help people who suffer from body-focused repetitive behaviors (BFRBs). Over 4% of Americans suffer from skin picking, hair pulling, and nail biting, the majority of whom resort to covering up the problem with makeup, gloves, wigs, and even tattoos due to treatment cost barriers and lack of effective tools to facilitate behavior change. While behavior therapy, and in particular habit reversal training, has shown efficacy, this method is traditionally burdened by unreliable journaling, a lack of access to treatment, and difficulty for patients to perform in real-time because of a lack of awareness. While real-time awareness devices do exist, there is room for improvement in detection accuracy. This project will integrate a novel sensor system into a wearable device that can lead to state-of-the-art detection accuracy of BFRB-related behaviors. This wearable sensor solution is the first of its kind, using the novel sensor to extract meaningful biomechanical information. This Small Business Innovation Research (SBIR) Phase II project will result in new behavior recognition algorithms, a new remote monitoring system, and new data generated from in-field experiments. The project will: 1) develop a new sensor calibration system and characterize signal artifacts that may influence detection accuracy; 2) develop new behavior detection algorithms using data captured in the lab; 3) conduct self-guided experiments in the field using the remote monitoring system proposed; and 4) refine recognition algorithms. Such sensitive measurements require ideal signal integrity, be sufficiently immune to signal artifacts, and tight electronics integration within wearable design constraints. This wearable system can profoundly impact the efficacy of habit reversal training during cognitive behavioral therapy, the leading method for reducing the negative effect of these behaviors.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.

这个小企业创新研究（SBIR）第二阶段项目的更广泛的影响/商业潜力将帮助那些患有身体集中重复行为（BFRB）的人。超过4%的美国人患有皮肤采摘，头发拉扯和咬指甲，其中大多数人诉诸于掩盖化妆，手套，假发，甚至纹身的问题，由于治疗成本的障碍和缺乏有效的工具，以促进行为改变。虽然行为疗法，特别是习惯逆转训练，已经显示出有效性，但这种方法传统上受到不可靠的日志记录，缺乏治疗途径以及由于缺乏意识而难以让患者实时执行的负担。虽然实时感知设备确实存在，但在检测准确性方面仍有改进的空间。该项目将把一种新型的传感器系统集成到可穿戴设备中，从而实现最先进的BFRB相关行为检测精度。 这种可穿戴传感器解决方案是同类产品中的第一个，使用新型传感器提取有意义的生物力学信息。这个小企业创新研究（SBIR）第二阶段项目将产生新的行为识别算法、新的远程监控系统以及从现场实验中生成的新数据。该项目将：1）开发新的传感器校准系统并表征可能影响检测准确性的信号伪影; 2）使用实验室捕获的数据开发新的行为检测算法; 3）使用所提出的远程监控系统在现场进行自我引导实验;以及4）改进识别算法。这种敏感的测量需要理想的信号完整性，充分免疫信号伪影，以及可穿戴设计约束内的紧密电子集成。这款可穿戴系统可以深刻影响认知行为治疗期间习惯逆转训练的效果，这是减少这些行为负面影响的主要方法。该奖项反映了NSF的法定使命，并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，被认为值得支持。
