Recently, Professor Hu Wenping and professor Bao Zhenan of Stanford University have made a breakthrough in the field of stretchable electronics and display, and their paper has been published in the international top academic journals science and Nature.Science: Focus on flexible human-computer interaction Systems based on stretchable optoelectronic devices. Flexible human-computer interaction systems based on stretchable optoelectronic devices are an important carrier and frontier for information technology transformation and integration into life processes.Through the topological flexible design of conductive polymer network, the mechanical and electrical properties of stretchable electrode materials are improved by order of magnitude.High temporal and spatial resolution electrophysiological monitoring of biological interface can be achieved by using the high density flexible array electrode.In particular, it has important clinical transformation value in accurately identifying important nerve nuclei, nerve conduction bundles and tumor functional boundaries in vulnerable parts such as brain stem.Related results are “Topological Supramolecular network enabled high conductivity,Stretchable Organic bioelectronics “(Science 2022, DOI: 10.1126/ science.ABJ7564).The corresponding authors are Professor Zhenan Bao of Stanford University and Associate Professor Yixuan Wang of Tianjin University.Stretchable light-emitting diodes are ideal devices for visual signal feedback in human-computer interaction systems and are at the forefront of flexible display technology.A high brightness all-polymer stretchable light-emitting diode was developed by flexible light-emitting polymer and trap “dilution” strategy combined with electrode material foundation and energy band engineering research.The integrated performance of intrinsic flexibility and luminance of the device is world leading.It is connected with flexible wireless power supply circuit to realize real-time display of pulse signal.This work opens up a new route for future display technology in material development and device preparation process.Published in the title “High-Brightness all-polymer stretchable LED with charge-trapping Dilution” (Nature 2022, DOI:10.1038 / s41586-022-04400-1).Zhitao Zhang, Weichen Wang, Yuanwen Jiang and Yixuan Wang from Tianjin University are co-first authors, and Zhenan Bao from Stanford University is the corresponding author.Source: tianjin university papers link https://www.science.org/doi/10.1126/science.abj7564https://www.nature.com/articles/s41586-022-04400-1
