Mechanically driven light generation is an exciting and under‐exploited phenomenon with a variety of possible practical applications. However, the current driving mode of mechanoluminescence (ML) devices needs strong stimuli. Here, a flexible sensitive ML device via nanodopant elasticity modulus modification is introduced. Rigid ZnS:M²⁺(Mn/Cu)@Al₂O₃ microparticles are dispersed into soft poly(dimethylsiloxane) (PDMS) film and printed out to form flexible devices. For various flexible and sensitive scenes, SiO₂ nanoparticles are adopted to adjust the elasticity modulus of the PDMS matrix. The doped nanoparticles can concentrate stress to ZnS:M²⁺(Mn/Cu)@Al₂O₃ microparticles and achieve intense ML under weak stimuli of the moving skin. The printed nano‐/microparticle‐doped matrix film can achieve skin‐driven ML, which can be adopted to present fetching augmented animations expressions. The printable ML film, amenable to large areas, low‐cost manufacturing, and mechanical softness will be versatile on stress visualization, luminescent sensors, and open definitely new functional skin with novel augmented animations expressions, the photonic skin.

通过纳米掺杂基质修饰的可打印皮肤驱动的机械发光设备

在许多可能的实际应用中，机械驱动的光产生是一种令人兴奋且开发不足的现象。但是，当前的机械发光（ML）设备的驱动模式需要强烈的刺激。在这里，介绍了一种通过纳米掺杂弹性模量修改的柔性灵敏ML器件。刚性ZnS：M ²⁺（Mn / Cu）@Al ₂ O ₃微粒被分散到柔软的聚二甲基硅氧烷（PDMS）膜中并打印出来以形成柔性器件。对于各种柔性和敏感场景，采用SiO ₂纳米颗粒来调节PDMS基质的弹性模量。掺杂的纳米颗粒可以将应力集中到ZnS：M ²⁺（Mn / Cu）@Al ₂ O _3上微粒，并在运动皮肤的弱刺激下达到强烈的ML。印刷的掺杂纳米/微粒的基质薄膜可以达到皮肤驱动的ML，可用于呈现提取的增强动画表达。可印刷的ML膜适用于大面积生产，低成本制造和机械柔软性，将在应力可视化，发光传感器以及具有新颖的增强动画效果的新型功能性皮肤（光子皮肤）上广泛应用。
