A three-dimensionally architected electronic skin mimicking human mechanosensation

【Abstract】

Human skin sensing of mechanical stimuli originates from transduction of mechanoreceptors that converts external forces into electrical signals that propagate to the central nervous system.  While imitating the spatial distribution of those mechanoreceptors can enable developments of electronic skins capable of decoupled sensing of normal/shear forces and strains, it remains elusive.  In this talk, I will introduce a three-dimensionally architected electronic skin (denoted as ‘3DAE-Skin’) with force and strain sensing components arranged in a 3D layout that mimics that of Merkel cells and Ruffini endings in human skin.  The 3D configuration of force and strain sensors and a heterogeneous encapsulation strategy enable the differentiation of normal or shear forces and induced strain.  Integration of the 3DAE-Skin with data acquisition/processing modules aided by deep learning algorithms allows development of a tactile system capable of normal/shear force sensing with spatial resolution comparable to human skin, as well as simultaneous modulus and curvature measurements through a simple touch of an object.  Demonstrations include rapid modulus measurements of fruits, bread and cake with various shapes and degrees of freshness.

人類皮膚對機械刺激的感知源于體內的機械感受器，這些感受器可將外力轉化為電信號，并通過中樞系統傳輸到大腦。模仿這些機械感受器的空間分布形式，使其能夠獨立感知壓力、剪切力和應變，可有效促進電子皮膚領域的發展，但相關工作鮮有報道。本報告將介紹一種具有三維架構的電子皮膚（簡稱“3DAE-Skin”），其亮點在于力和應變傳感器的空間布局，這一布局模仿了人類皮膚中的Merkel細胞和Ruffini小體的空間分布。這種傳感器的空間分布和所提出的異質封裝策略使3DAE-Skin具備了出色的解耦測量能力，能夠同時解耦測量壓力、剪切力和應變。將該電子皮膚器件與信號處理模塊、深度學習算法相結合，開發出具有與人類皮膚感知空間分辨率相當的人工觸覺系統，該系統通過簡單的觸摸操作即可同時測量物體局部的彈性模量和主曲率。為展示該觸覺系統的實際應用價值，我們利用該系統測量了具有不同形狀的水果、面包等食物的新鮮度隨時間的變化。
