Ultra-Flexible "Ionic E-Skin" for Direct Communication Between Biological Systems and Electronics

虽然最初开发一种可以弥合电子系统和生物系统之间差距的新型“电子皮肤”(离子e-皮肤)的项目还没有完成，但这位研究员在追求最初目标的同时能够有一个侧重点的发现。具体地说，这位研究员发现了一种制造超灵活、可伸缩滤色器的方法。这些滤色器不仅具有优于所有先前文献示例的机械性能，而且即使在重复变形之后也显著地没有表现出性能退化。尽管这不是我们最初的目标，但在现实中，这些结果是重要的，主要有两个原因。首先，尽管存在许多依赖于光学现象和包含光学元件的可穿戴设备的超柔性传感器的例子，但具有匹配机械性能的滤色器还不存在。由于滤色器很简单，但在许多技术中高度相关，因此极易变形滤色器的发明为需要使用特殊形状或与超柔性光学设备集成的场合打开了可能性。其次，发现的策略不仅限于所使用的演示材料。相反，该策略代表了一种通用的方法，可以与符合该方法基本原则的任何材料组合一起使用。因此，我们能够制作一份出版物(《常识》)。等，高级选项马特。2018年，6,1800851)，并在一个国际会议上展示这项工作(2018年秋季会议和展览，美国马萨诸塞州波士顿)。

Although the original project to develop a new type of "e-skin” (ionic e-skin) that can bridge the gap between electronic and biological systems is not yet complete, the Fellow was able to make a side discovery while in pursuit of the original goal. Specifically, the Fellow discovered a strategy for making ultraflexible, stretchable color filters. Not only do these color filters possess mechanical properties superior to all previous literature examples, they also remarkably show no performance degradation even after repeated deformation. Although it was not the original objective that we were aiming for, in reality these results were significant for two main reasons. First, although numerous examples of ultraflexible sensors reliant on optical phenomena and wearable devices containing optical elements exist, color filters with matching mechanical properties did not yet exist. As color filters are simple yet highly-relevant in many technologies, the invention of an extremely deformable color filter opens up possibilities for use where unusual form factors or integration with ultraflexible optical devices is necessary. Second, the discovered strategy is not just limited to the demonstrates materials used. Rather, the strategy represents a generalized method and can be used with any combination of materials that adheres to the underlying principles of the method. As a result, we were able to produce one publication (Ordinario et. al., Adv. Opt. Mater. 2018, 6, 1800851) and present the work at an international conference (MRS Fall Meeting and Exhibit 2018, Boston, MA, USA).
