Stretchable electronic devices fabricated using isobutylene-based materials

未来的电子设备将建造在柔软的聚合材料上，使它们具有可拉伸、可扭曲和可变形的特性。这种可拉伸性使得当前刚性材料无法实现的应用，例如柔性照明，显示器和太阳能电池；用于机器人的柔软的、对压力敏感的皮肤；和符合生物医学传感器，可以层压在皮肤上或植入人体，以检测和显示信息。然而，在可拉伸电子产品的研究中，专门使用了可拉伸硅橡胶材料，这种材料对氧气和水分的渗透性很强，严重降解了器件中的有机电子材料，大大缩短了器件的使用寿命。我们的研究旨在通过实现一种不同的可拉伸材料——丁基橡胶来解决这个问题，丁基橡胶以其不透湿和不透氧而闻名。我们将证明丁基橡胶的不渗透性和柔软的机械性能可以生产可拉伸的有机发光器件和有机太阳能电池，在环境条件下实现长期运行。

Electronic devices of the future will be built on soft, polymeric materials, making them stretchable, twistable, and deformable. This stretchability enables applications impossible to achieve with current rigid materials, such as flexible lighting, displays, and solar cells; soft, pressure-sensitive skins for robotics; and conformable biomedical sensors that can be laminated on skin or implanted into the human body to detect and display information. Research in stretchable electronics, however, has exclusively used stretchable silicone rubber materials that are highly permeable to oxygen and moisture, which severely degrade the organic electronic materials in the devices and drastically shorten device lifetime. Our research aims to solve this problem by implementing a different stretchable material - butyl rubber - that is notable for its impermeability to moisture and oxygen. We will demonstrate that the impermeability and soft mechanical properties of butyl rubber can produce stretchable organic light-emitting devices and organic solar cells that achieve long-term operation under ambient conditions.
