Electronic tattoos have great potential in health and movement sensing applications on the skin. However, existing electronic tattoos cannot be conformal, sticky, and multilayered at the same time. Here, we have achieved multilayered integration of the electronic tattoo that is highly stretchable (800%), conformal, and sticky. This electronic tattoo can enable the crease amplification effect, which can amplify the output signal of integrated strain sensors by three times. The tattoo can be transferred to different surfaces and form a firm attachment, where no solvent or heat is needed. The tattoo fabrication is straightforward and scalable; a layer-by-layer strategy and two materials (metal-polymer conductors and the elastomeric block copolymer) are used to fabricate the circuit module with desirable numbers of layers within the tattoo. A three-layered tattoo integrating 1 heater and 15 strain sensors is developed for temperature adjustment, movement monitoring, and remote control of robots.

可实现折痕放大效果的多层电子转印纹身

电子纹身在皮肤上的健康和运动感应应用方面具有巨大潜力。然而,现有的电子纹身不能同时具有保形性、粘性和多层性。在这里,我们实现了高度可拉伸(800%)、保形和粘性的电子纹身的多层集成。这种电子纹身可以实现折痕放大效果,可以将集成应变传感器的输出信号放大三倍。纹身可以转移到不同的表面并形成牢固的附着,不需要溶剂或加热。纹身制作简单且可扩展;采用逐层策略和两种材料(金属聚合物导体和弹性嵌段共聚物)来制造在纹身内具有所需层数的电路模块。
