Dynamic thermal emitters based on thermally triggered modes exhibit the unique superiority of adaptive responsiveness and zero-power operation, whereas they are accompanied by either low emission tunability or lack of customizability due to the limitations of single-actuation mechanism. We herein present a novel co-actuation strategy, which is based on the coupling of thermochromism and thermal deformation in a manganite perovskite-based resonator, to synergistically modulate thermal emission. Dynamic thermal emitter based on the co-actuation strategy exhibits a remarkably tunable emittance contrast of 0.61 within the full-wave infrared (FWIR: 2.5-25μm) region and a customizable transition at room temperature of 293 K. Only optimizing the thickness of manganite, the resonator can be developed as an adaptive camouflage device, a spectral selective absorber, or a thermal management device. Moreover, our design imparts the brittle manganite ceramics with excellent mechanical flexibility, making the resonator facile for integrating with the flat or curved configurations. The proposed strategy may enable a versatile manganite perovskite-based platform for the thermal science community.

基于热触发模式的动态热辐射器具有自适应响应能力和零功率运行的独特优势，但由于单驱动机制的局限性，它们伴随着低发射可调性或缺乏可定制性。我们在此提出一种新颖的共激励策略，该策略基于热变色和锰酸钙钛矿基谐振器中热变形的耦合，以协同调制热辐射。基于共同驱动策略的动态热辐射器在全波红外（FWIR：2.5-25μm）区域内具有0.61的显着可调发射率对比度，在293 K的室温下可自定义转变。仅优化锰矿的厚度，谐振器可以开发为自适应伪装设备，光谱选择性吸收器或热管理装置。此外，我们的设计为脆性锰铁陶瓷赋予了出色的机械柔韧性，使谐振器易于与平面或弯曲配置集成。提出的策略可以为热科学界提供一个基于多功能锰铁钙钛矿的平台。
