展示了一种新型的可纹身的、可印刷的、绿色有机发光二极管（OLED），其制造在商业临时纹身纸的顶部上。转移机制依赖于通常结合在纸纹身中的牺牲层的溶解。该即用型装置可以储存在纹身基质上，并在稍后的时间释放在目标表面上，简单地通过用水稍微润湿纹身纸。这种方法提供了一种在几乎任何表面上转移OLED的快速简便的方法。这对于皮肤上和一次性电子应用而言是特别有吸引力的。概念验证首次证明了可操作OLED纹身的可行性。虽然这种器件的性能还不能与刚性或柔性不可纹身基板上的OLED相比，但结果显示了OLED纹身技术在集成整合电子电路中的潜力。
A novel tattooable, ultrathin, green organic light-emitting diode (OLED) fabricated on top of commercial temporary tattoo paper, is demonstrated. The transfer mechanism relies on dissolution of the sacrificial layer typically incorporated in paper-tattoos. The ready-to-use device can be stored on the tattoo substrate and released on the target surface at a later time, simply by a slight wetting of the tattoo paper with water. This approach provides a quick and easy method of transferring OLEDs on virtually any surface. This is particularly appealing, in perspective, for on-skin and disposable electronic applications. The proof of concept demonstrates, for the very first time, the feasibility of ultrathin operational OLED tattoos. While the performance of such devices is not yet comparable with that of OLEDs on rigid or flexible non-tattooable substrates, the results show the potential for an OLED tattoo technology in integrated conformable electronic circuits.
