新型伸缩太阳能电池成为人造电子“超级皮肤”的电源

人工皮肤的基础是一个有弹性的有机晶体管,由柔性聚合物和碳基材料制成。
斯坦福大学研究人员包哲楠(Bao Zhenan)希望创造“超级皮肤。科学家们正努力增加其检测化学品、感觉各种生物分子的能力。她也正努力使皮肤实现自供电,使用聚合物太阳能电池发电。新太阳能电池不仅灵活,而且弹性好,可以被伸展长度超出原有长度的30%,并在无任何电能损害和丢失的情况下反弹回来。 “有了人工皮肤,基本上可以涵盖我们所希望具备的任何功能。”包女士是化学工程系的教授。

人工皮肤的基础是一个有弹性的有机晶体管,由柔性聚合物和碳基材料制成。为了实现触摸感应,晶体管包含了一个薄的、高弹性橡胶层,被塑造成一个微小的倒金字塔网格形。一旦受压,这层的厚度发生变化,从而通过晶体管改变电流。对应所需的灵敏度水平,该传感器每平方厘米拥有从几十万到2500万个金字塔。
