摘要

Abstract

Camouflage technology has garnered increasing attention for various applications. With the continuous advancement of detection technologies and the increasing variability of camouflage scenarios

the demand for multispectral dynamic camouflage has been steadily growing. In this work

we present a multispectral dynamic regulator based on phase-changing material vanadium dioxide (VO

) that can be dynamically and functional-independently regulated for reflective color and thermal radiation. It has been shown that the device can achieve a wide color gamut variation in visible band while simultaneously achieving highest emissivity tunability (Δ

=-0.58) in the atmospheric window up to now

achieves multispectral camouflage spanning the visible and infrared spectra among VO

-based devices. To go a step further

we advance the device featuring long-term cycling stability to achieve thermal-electric dual-mode response and flexibility for a series real-world camouflage performance evaluation. We have also demonstrated the digital camouflage based on multispectral dynamic regulator through Neighboring Color Block Camouflage Algorithm

highlighting its potential for practical implementation in different camouflage scenarios. The device achieves multispectral dynamic camouflage

opening a path for advancing the technology development in both the scientific fie

ld and practical applications.
