Making color display cool: An electrochemical self-cooled dynamic structural color device

“…Required heat dissipation of different display technologies (WO3-based multilayered film 14 , WO3-based metamaterial 39 , conventional RMED devices 17,40,43,44 , dynamic photonic crystal 41,45,46 , liquid crystal 42 , and our DCMRCs) in the summer of Shanghai.…”

“…There are not yet EC devices that can realize reversible color-changing while preserving high solar reflection. 14,17,[39][40][41][42][43][44][45][46][47][48][49] .…”

Flexible Transparent Conductive Films of Ag/Cr2O3 Core–Shell Nanowires as Electrodes for Electroluminescent Devices and Heaters

“…Flexible transparent conductive films (TCFs) have wide application prospects in solarcells, − wide-band antenna, − electrochromic devices, − electroluminescent devices, − wearable sensors, − flexible heaters, − light emitting diodes, − etc. Due to their excellent optical-electrical performances, mechanical flexibility, simple and diverse preparation methods, and the ability to be deposited on different substrates, silver nanowires (Ag NWs) have become a common research material for the preparation of TCFs and are an important part of the next generation of flexible optoelectronic devices.…”

A multifunctional structural coloured electronic skin monitoring body motion and temperature

“…The degassed suspension was drop cast (step 5) on top of a AgNW/PET substrate, prepared by gravure printing a conductive AgNW-based ink (see ESI †). 29 After solvent evaporation (step 6), the dried polymer film was peeled off the PET substrate (step 7), obtaining the free-standing PDCLC/AgNW film. In the final stage, conductive epoxy glue and wires were attached to the photonic film to induce proper electrical contact between the power source and the device (step 8).…”

“…2a and b). 21,29,30 Easily distinguishable colours were observed for temperature changes per 1 1C, hence these photonic wearables are suitable for the detection of subtle body temperature variations via optical feedback.…”
