我们报告的电子系统，实现厚度，有效弹性模量，弯曲刚度，和面积质量密度匹配的表皮类。与传统的基于晶片的技术不同，将这样的装置层压到皮肤上导致仅基于货车德瓦耳斯相互作用的适形接触和足够的粘附，其方式对使用者是机械不可见的。我们描述的系统，包括电生理，温度和应变传感器，以及晶体管，发光二极管，光电探测器，射频电感器，电容器，振荡器和整流二极管。太阳能电池和无线线圈提供了供电选择。我们使用这种类型的技术来测量心脏，大脑和骨骼肌产生的电活动，并表明所产生的数据包含足够的信息来制作一种不寻常的电脑游戏控制器。
We report classes of electronic systems that achieve thicknesses, effective elastic moduli, bending stiffnesses, and areal mass densities matched to the epidermis. Unlike traditional wafer-based technologies, laminating such devices onto the skin leads to conformal contact and adequate adhesion based on van der Waals interactions alone, in a manner that is mechanically invisible to the user. We describe systems incorporating electrophysiological, temperature, and strain sensors, as well as transistors, light-emitting diodes, photodetectors, radio frequency inductors, capacitors, oscillators, and rectifying diodes. Solar cells and wireless coils provide options for power supply. We used this type of technology to measure electrical activity produced by the heart, brain, and skeletal muscles and show that the resulting data contain sufficient information for an unusual type of computer game controller.
