“…14d). 166 Using patterned liquid metal Galinstan interconnections, a stretchable array of the EC devices was fabricated based on a strain-relieving mechanism with an island-bridge design, resulting in mechanical stability to repeated stretching of up to 30%. The interactive display system could measure the strain due to wrist bending and the skin temperature by the sensors and display changes in the colour pattern of the EC array aided by the Arduino circuit (Fig.…”

“…In addition, they further designed a P3HT/WO 3 -based EC arrays for displaying skin temperature and joint motion. 136 As shown in Figure 15d, a stretchable array of ECDs with liquid metal interconnections was fabricated onto the Ecoflex substrate and then incorporated with the strain and temperature sensors via the Arduino circuit. With this system, the joint motions and skin temperature changes could be independently displayed as changes in color pattern of the EC arrays, providing visual feedbacks for multiple stimuli.…”

A wearable interactive device that can synchronously detect and visualize pressure, stimuli will supplement easily identifiable in situ signals with conventional sensing that outputs only electronic signals. Currently, most interactive devices are composed of physically connected separate pressure sensors and display elements, which do not conform to the development of miniaturization and high integration. The realization of combining these two functions in one device with a simplified configuration is still only beginning to be explored. Inspired by the two-in-one response of the octopus, which can both sense and visualize stimuli, an integrated hybrid device based on ionic sensing and electrochromic display is proposed for interactive pressure perception. By efficiently reusing the electrodes and ionic gel, the device enables quantitative sensing and direct color changing in response to pressure. Benefiting from its excellent comprehensive performance, the applications are explored and verified, including the interactive perception of pressure information, hiding and display of visual information under pressure regulation, and repeated writing and erasing on flexible boards. Notably, multiple customized systems with improved design flexibility are implemented to provide remote monitoring and visual warning of behavioral states and physiological parameters. This study diversifies solutions to realize a direct link between pressure detection and visualization.
