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

Abstract

Visual interactive devices have become the main focus of intelligent applications in modern society. Based on the controllable storage and release characteristics of microcapsules and the visual display effect of electroluminescent devices, a new visual pressure interactive display of alternating current electroluminescent (VPI-ACEL) devices is developed by combining with the release of materials inside the microcapsule that can trigger the luminescence of light-emitting devices under special conditions. The prepared hydrogel microcapsules are proven to have the advantages of environmental protection, stability, and pressure sensitivity. With the force acting on the interaction layer greater than 1.5 N, the luminous brightness of the device can reach 80 cd m−2 (180 V, 2000 Hz). Moreover, the device can accurately judge the stress position and has excellent interaction effects and visual feedback. Specifically, the VPI-ACEL device is successfully combined with the packaging box to simulate the application of packaging collision detection. Finally, the device is expected to be directly used in the field of lightweight pressure monitoring to promote the development of visual monitoring.
