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.

未来的电子设备将建立在柔软的聚合物材料上，使其可拉伸、可扭曲和可变形。这种可伸缩性使目前的刚性材料无法实现的应用，如柔性照明、显示器和太阳能电池；机器人的柔软、压敏皮肤；以及可层叠在皮肤上或植入人体以检测和显示信息的适形生物医学传感器。然而，在可拉伸电子设备的研究中，只使用了对氧气和湿度具有高度渗透性的可拉伸硅橡胶材料，这严重降解了设备中的有机电子材料，并极大地缩短了设备的寿命。我们的研究旨在通过实现一种不同的可伸缩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。我们将展示丁基橡胶的不渗透性和软机械性能，可以制造出可伸缩的有机发光器件和有机太阳能电池，实现在环境条件下的长期运行。
