无机发光二极管和光电探测器是固态照明、数字成像及许多其他应用中重要的成熟技术。消除支撑半导体晶圆带来的机械和几何设计限制，能够使其在生物医学和机器人技术等领域有其他用途。在此我们描述了一些系统，它们由相互连接的超薄无机发光二极管和光电探测器阵列组成，这些阵列以机械优化的布局配置在特殊的基底上。可发光的缝合线、可植入的薄片以及可完全浸入生物流体的发光等离子体晶体，说明了这些技术在生物医学中的适用性。能够贴合地集成在手套曲面的防水光学接近传感器胶带，以及缠绕在静脉注射系统管道上的薄型折射率监测器，展示了在机器人技术和临床医学中的可能性。这些及相关系统可能会为光电器件创造重要的非传统机遇。
Inorganic light-emitting diodes and photodetectors represent important, established technologies for solid-state lighting, digital imaging and many other applications. Eliminating mechanical and geometrical design constraints imposed by the supporting semiconductor wafers can enable alternative uses in areas such as biomedicine and robotics. Here we describe systems that consist of arrays of interconnected, ultrathin inorganic light-emitting diodes and photodetectors configured in mechanically optimized layouts on unusual substrates. Light-emitting sutures, implantable sheets and illuminated plasmonic crystals that are compatible with complete immersion in biofluids illustrate the suitability of these technologies for use in biomedicine. Waterproof optical-proximity-sensor tapes capable of conformal integration on curved surfaces of gloves and thin, refractive-index monitors wrapped on tubing for intravenous delivery systems demonstrate possibilities in robotics and clinical medicine. These and related systems may create important, unconventional opportunities for optoelectronic devices.
