Abstract

Tactile visual synapses combine the functionality of tactile artificial synapses with the ability to visualize their activity in real time and provide a direct and intuitive visualization of the activity, offering an efficient route for in situ health monitoring. Herein we present a tactile visual synapse that enables in situ monitoring of finger rehabilitation and electrocardiogram analysis. Repetitive finger flexion and various arrhythmias are monitored and visually guided using the developed tactile visual synapse combined with an electrical and optical output feedback algorithm. The tactile visual synapse has the structure of an electrochemical transistor comprising an elastomeric top gate as a tactile receptor and an electrochemiluminescent ion gel as a light-emitting layer stacked on a polymeric semiconductor layer, forming an electrical synaptic channel between source and drain electrodes. The low-power (~34 μW) visualization of the tactile synaptic activity associated with the repetitive motions of fingers and heartbeats enables the development of a convenient and efficient personalized healthcare system.

电化学发光触觉视觉突触实现原位健康监测
触觉视觉突触将触觉人工突触的功能与实时可视化其活动的能力相结合,提供了直接直观的活动可视化,为原位健康监测提供了有效途径。在这里,我们提出了一个触觉视觉突触,使手指康复和心电图分析的原位监测。使用已开发的触觉视觉突触结合电和光输出反馈算法,监测和视觉引导重复性手指屈曲和各种心律失常。触觉视觉突触具有电化学晶体管结构,包括弹性顶栅作为触觉感受器和电化学发光离子凝胶作为发光层堆叠在聚合物半导体层上,在源极和漏极之间形成电突触通道。低功率(~34 μW)可视化与手指和心跳重复运动相关的触觉突触活动,使开发方便高效的个性化医疗保健系统成为可能。

期刊介绍: Nature Materials is a monthly multi-disciplinary journal aimed at bringing together cutting-edge research across the entire spectrum of materials science and engineering. It covers all applied and fundamental aspects of the synthesis/processing, structure/composition, properties, and performance of materials. The journal recognizes that materials research has an increasing impact on classical disciplines such as physics, chemistry, and biology. Additionally, Nature Materials provides a forum for the development of a common identity among materials scientists and encourages interdisciplinary collaboration. It takes an integrated and balanced approach to all areas of materials research, fostering the exchange of ideas between scientists involved in different disciplines. Nature Materials is an invaluable resource for scientists in academia and industry who are active in discovering and developing materials and materials-related concepts. It offers engaging and informative papers of exceptional significance and quality, with the aim of influencing the development of society in the future.
