Abstract

A rubbery stretchable conductor with high conductivity and transparency is crucial for the development of rubbery stretchable vertical-structured photodetectors. However, the development of such a rubbery conductor is still nascent. Here, we report the scalable manufacturing of rubbery stretchable transparent conductors (RSTCs) and the development of a rubbery stretchable vertical-structured photodetector (RSVPD). The RSTC is fabricated into a specialized micromesh structure by utilizing a close-packed monolayer of polystyrene microspheres as a mask. The micromesh structure not only enhances the conductor’s stretchability and transparency but also maintains its conductivity, making it ideal for various applications in stretchable electronics. The RSTCs are used to construct RSVPDs that have high response over a broad spectrum, and their electrical performances can be retained even when subjected to mechanical strains of up to 50%. Furthermore, a stretchable imager based on RSVPD was developed to detect the multipoint light distribution. Lastly, a photoplethysmography (PPG) sensor was also developed for real-time health monitoring.

基于橡胶可拉伸透明导体的宽带响应橡胶可拉伸垂直结构光电探测器

具有高导电性和透明性的橡胶可拉伸导体是开发橡胶可拉伸垂直结构光电探测器的关键。然而，这种橡胶导体的发展仍处于初期阶段。在这里，我们报告了橡胶可拉伸透明导体（RSTCs）的可扩展制造和橡胶可拉伸垂直结构光电探测器（RSVPD）的开发。RSTC是利用聚苯乙烯微球的致密单层作为掩膜制成的专用微网结构。微孔结构不仅增强了导体的可拉伸性和透明度，而且保持了其导电性，使其成为可拉伸电子产品中各种应用的理想选择。RSTCs用于构建rsvpd，在广谱范围内具有高响应，即使在高达50%的机械应变下也能保持其电气性能。在此基础上，研制了一种基于RSVPD的可伸缩成像仪，用于多点光分布检测。最后，还开发了用于实时健康监测的光电容积脉搏波传感器。
