Social touch is a natural mode of communication between people and better understanding of how to convey social touch mechanistically will result in new forms of communication and increased capabilities of wearable devices that improve human health and quality of life. The importance of social touch is becoming more evident as we increase remote communication through email, text messages and videoconferencing. Prior work has shown that social touch can be replicated through wearable and holdable devices, but current devices are bulky and impractical. This research will combine principles of soft robotics and knit textiles of varying stiffness to design and fabricate a new kind of soft wearable haptic device, in which careful specification of stitch size, placement, and material in a knit sleeve will control the deformation of pneumatic bladders that apply force to the wearer. Project outcomes will advance knowledge in the field of social touch and human perception, and will lay the foundation for a variety of other types of knit-textile-based devices, including soft assistive devices. Additional broad impact will derive from activities designed to broaden participation of underrepresented groups in engineering through lab tours, outreach programs, and mentoring of students from groups that are underrepresented in engineering, and by making project findings available to a wide audience through an open-source materials library.Current soft wearable devices are bulky and impractical because they need stiff frames to ensure load transmission. The pixel-like control of material properties afforded by multi-material and multi-stitch knit textiles, on the other hand, can redirect force transmission to precise deformation modes efficiently and with a low profile. This project approaches designing, fabricating, and testing knit-enabled wearable devices in three thrusts. The first thrust will model and optimize knits to achieve target load and deformation profiles by using a combination of experimental material characterization and multiscale modeling to harness the full capabilities of the modern knitting process. The second thrust will design, fabricate, and test wearable pneumatic devices, including consideration for donning and doffing, actuator integration and interfacing, and device characterization. The third thrust will implement and test social touch cues using the device with pre-programmed haptic emojis and display of teleoperated social touch queues in real time. Taken together, these thrusts will create new forms of communication and lead to increased capabilities of wearable devices that improve human health and quality of life.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.

社交接触是人与人之间交流的一种自然模式，更好地理解如何机械地传达社交接触将带来新的交流形式并增强可穿戴设备的功能，从而改善人类健康和生活质量。随着我们通过电子邮件、短信和视频会议增加远程沟通，社交接触的重要性变得越来越明显。先前的研究表明，社交接触可以通过可穿戴和可握持设备来复制，但当前的设备体积庞大且不切实际。这项研究将结合软机器人和不同刚度的针织纺织品的原理，设计和制造一种新型软可穿戴触觉设备，其中针织套筒中的针脚尺寸、位置和材料的仔细规范将控制气囊的变形向佩戴者施加力。项目成果将增进社会接触和人类感知领域的知识，并将为各种其他类型的基于针织纺织品的设备（包括软辅助设备）奠定基础。额外的广泛影响将来自于旨在扩大工程领域代表性不足群体参与的活动，这些活动包括实验室参观、外展计划、对工程领域代表性不足群体的学生进行指导，以及通过开源项目向广大受众提供项目成果。材料库。当前的软可穿戴设备体积庞大且不实用，因为它们需要刚性框架来确保负载传输。另一方面，多材料和多针针织纺织品提供的材料属性的像素式控制可以有效且低调地将力传输重定向到精确的变形模式。该项目通过三个重点来设计、制造和测试针织可穿戴设备。第一个重点将通过结合实验材料表征和多尺度建模来建模和优化针织物，以实现目标载荷和变形轮廓，以利用现代针织工艺的全部功能。第二个重点将设计、制造和测试可穿戴气动设备，包括考虑穿脱、执行器集成和接口以及设备表征。第三个重点将使用带有预编程触觉表情符号的设备来实现和测试社交触摸提示，并实时显示远程操作的社交触摸队列。总而言之，这些推动力将创造新的通信形式，并提高可穿戴设备的功能，从而改善人类健康和生活质量。该奖项反映了 NSF 的法定使命，并通过利用基金会的智力优势和更广泛的评估进行评估，认为值得支持。影响审查标准。
