A three-dimensionally architected electronic skin mimicking human mechanosensation

Science, Год журнала: 2024, Номер 384(6699), С. 987 - 994

Опубликована: Май 30, 2024

Human skin sensing of mechanical stimuli originates from transduction mechanoreceptors that converts external forces into electrical signals. Although imitating the spatial distribution those can enable developments electronic skins capable decoupled normal/shear and strains, it remains elusive. We report a three-dimensionally (3D) architected (denoted as 3DAE-Skin) with force strain components arranged in 3D layout mimics Merkel cells Ruffini endings human skin. This 3DAE-Skin shows excellent performances normal force, shear enables development tactile system for simultaneous modulus/curvature measurements an object through touch. Demonstrations include rapid modulus fruits, bread, cake various shapes degrees freshness.

A Semi‐Interpenetrating Poly(Ionic Liquid) Network‐Driven Low Hysteresis and Transparent Hydrogel as a Self‐Powered Multifunctional Sensor

Advanced Functional Materials, Год журнала: 2024, Номер 34(32)

Опубликована: Май 6, 2024

Abstract Conductive hydrogels are gaining significant attention as promising candidates for the fabrication materials flexible electronics. Nevertheless, improving tensile properties, hysteresis, durability, adhesion, and electrochemical properties of these remains challenging. This work reports development a novel semi‐interpenetrating network poly(ionic liquid) hydrogel named PATV, via in situ polymerization acrylamide, N ‐[Tris(hydroxymethyl)methyl] 1‐vinyl‐3‐butylimidazolium tetrafluoroborate. The density functional theory calculations reveal that acts physical cross–linking points to construct hydrogen‐bond networks. Furthermore, networks dissipate energy efficiently quickly, thus stress concentration hysteresis avoided. prepared has low (9%), high (900%), fast response (180 ms), sensitivity (gauge factor = 10.4, pressure 0.14 kPa −1 ), wide sensing range (tensile range: 1–600%, compression 0.1–20 kPa). A multifunctional sensor designed based on enables real‐time, rapid, stable response‐ability detection human movement, facial expression recognition, pronunciation, pulse, handwriting, Morse code encryption. assembled triboelectric nanogenerator displays an excellent harvesting capability, highlighting its potential application self‐powered wearable electronic devices.
