Abstract In the field of wearable electronics and human–machine interfaces, there is a growing need for highly sensitive adaptable sensors capable detecting wide range stimuli with high precision. Traditional often lack versatility to adjust their sensitivity different applications. Inspired by mechanosensory system spiders, shape‐reconfigurable crack‐based sensor ultrahigh tunable strain based on precise control nanocrack formation shape memory polymer substrate demonstrated. This design...
Stretchable sound-in-displays, which can generate synchronous sound and light directly from the display without a separate speaker, allow immersive audio visual perception even on curved surfaces. In stretchable alternating current electroluminescent (ACEL) devices have been used as light-emitting sources owing to their high brightness stability. However, ACEL that use low dielectric constant (κ) materials require operating voltage for generating sound. Herein, we demonstrate loudspeaker...
Using an energy filter in transmission electron microscopy has enabled elemental mapping at the atomic scale and improved precision of structural determination by gating inelastic elastic imaging electrons, respectively. Here, we use ultrafast to enhance temporal resolution toward domain motion. Visualizing transient structures with femtosecond was achieved selecting electrons a narrow distribution from dense chirped photoelectron packets broad longitudinal momentum distributions thus...
Abstract The growing importance of human–machine interfaces and the rapid expansion internet things (IoT) have inspired integration displays with sound generation systems to afford stretchable sound‐in‐display devices thus establish human‐to‐machine connections via auditory system visualization. Herein, synchronized color is demonstrated for a device electrodes strain‐insensitive silver nanowires (AgNWs) emissive layers field‐induced inorganic electroluminescent (EL) phosphors. In this...
