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.

社交触觉是人们之间自然的沟通方式，并且更好地了解如何机械地传达社会触摸将导致新的沟通形式和可穿戴设备的能力提高，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，社交触觉的重要性变得越来越明显。先前的工作表明，可以通过可穿戴和可固定设备复制社交触觉，但是当前的设备笨重且不切实际。这项研究将结合柔软的机器人技术和针织纺织品的原理，以不同的刚度来设计和制造一种新型柔软的可穿戴触觉设备，其中仔细规定了针织套筒中的针迹尺寸，放置和材料，将控制对佩戴者施加强力的气孔的变形。项目成果将促进社交和人类感知领域的知识，并为各种其他类型的基于编织的设备（包括软辅助设备）奠定基础。旨在通过实验室游览，外展计划以及对工程中代表性不足的学生的指导，通过实验室游览，指导学生的活动来扩大代表性不足的团体的活动的额外广泛影响，并通过使项目发现可以通过开源材料库向广泛的受众提供。易于耐磨设备可以确保稳固的装置，因为它们需要强大的固定式运输量，以确保负载固定的Framement。另一方面，由多材料和多缝针织纺织品提供的像素状控制材料特性可以有效地且较低。该项目接近设计，制造和测试以三个推力的针织可穿戴设备的设计。第一个推力将通过使用实验材料表征和多尺度建模的组合来实现目标负载和变形轮廓进行建模和优化，以实现现代编织过程的全部功能。第二个推力将设计，制造和测试可穿戴的气动设备，包括考虑doning和Doffing，执行器集成和接口以及设备表征的考虑。第三个推力将使用该设备具有预先编程的触觉表情符号，并实时展示该设备，并实时实现和测试社交接触线索。综上所述，这些推力将创造新形式的沟通形式，并提高可穿戴设备的能力，从而改善人类健康和生活质量。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估评估标准的评估值得支持的。
