Visual pressure interactive display of alternating current electroluminescent devices based on hydrogel microcapsules

Abstract

Visual interactive devices have become the main focus of intelligent application in modern society. Based on the controllable storage and release characteristics of microcapsules and the visual display effect of...

Nature‐Inspired Pressure Interactive Alternating Current Electroluminescent for Orientation Indication, Visual Sensing, and Remote Monitoring

“…In contrast, the solvent retaining ability and recyclability were greatly improved in this work. [ 25 ] By utilizing cavity environments from the grid layer, the elastic recovery ability of the composite hydrogel, and the low saturated vapor pressure of LiBr, we have successfully addressed all of the aforementioned challenges. As demonstrated in Figure 6d, the duration of maximum brightness maintenance for MPI‐ACEL (L) was observed under different environments following the application of pressure (50 N).…”

“…Nonetheless, technological limitations prevented the resolution of issues related to wide dynamic range pressure identification, recycling, and long-term storage. [25,26] Therefore, the development of an accurate visual pressure sensing device, integrating the two functions through suitable composite materials and effective structural modifications, is urgently needed.…”

Dual-response thermosensitive microcapsules based on hydrogel

“…In this work, based on previously reported thermal expansion microcapsules, [18][19][20] thermosensitive microcapsules (TSMs) with single-stimulus dual-response nature were prepared by incorporating colour-changing materials. TSMs are characterized by colour change and expansion under different temperatures.…”

Solid-State Displacement Synthesis of Alkaline-Earth Selenide for White Emission through Alternating Current Electroluminescence

“…The reduction of luminous efficiency in thick devices was ascribed to increased loss of light transmittance. 39 We further characterized the device with a d C of 60 μm that exhibited white emissions. Figure 4f shows the emission intensity of the device as a function of applied voltages in the 100−500 V range at different frequencies (see Figures S11 for the corresponding spectra).…”

“…The luminous efficiency for devices with a d C of about 30, 60, and 90 μm was further determined to be 10.51, 6.24, and 1.67 cd (W·m 2 ) −1 , respectively. The reduction of luminous efficiency in thick devices was ascribed to increased loss of light transmittance …”
