讲座摘要:

Human skin sensing of mechanical stimuli originates from transduction of mechanoreceptors that converts external forces into electrical signals.  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.  This 3DAE-Skin shows excellent decoupled sensing performances of normal force, shear force and 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.
