In this work, self-assembled amino-acid appended perylene bisimides (PBIs) have been studied that when processed into thin films change their resistivity in response to being bent. The PBIs assemble into structures in water and form thin films upon drying. These normally delicate thin films can be tolerant to bending, depending on the aggregates they form. Furthermore, the films then reversibly change their resistivity in response to this mechanical stimulus. This change is proportional to the degree of bending of the film giving them the potential to be used quantitatively to measure mechanical movement, such as in wearable devices.
在这项工作中，对自组装的 appended 氨基酸苝二酰亚胺（PBIs）进行了研究，当将其加工成薄膜时，它们会因弯曲而改变电阻率。PBIs 在水中组装成结构，并在干燥时形成薄膜。这些通常很脆弱的薄膜能够耐受弯曲，这取决于它们形成的聚集体。此外，这些薄膜随后会因这种机械刺激而可逆地改变其电阻率。这种变化与薄膜的弯曲程度成正比，这使它们有潜力被定量用于测量机械运动，例如在可穿戴设备中。
