Transient electronic devices can help eliminate the growing environmental problem of “electronic pollution.” However, their applications are severely limited by poor optoelectronic performance. Here, a new degradable polymeric dielectric material is synthesized by a one-step method for organic neuromorphic vision sensors (ONeuVSs). A high mobility of 2.74 cm V s and current on/off ratio greater than 10 were obtained. Moreover, we achieved excellent optical figures of merit with a maximum photosensitivity of 8.7 × 10 and maximum detectivity of 9.42 × 10 Jones, which are the best values among transient electronic devices. The ONeuVS array could perform static image recognition with an accuracy of 92.7% and high-pass filtering behavior. More interestingly, both high-performance optical synapses and switching functional devices could be realized by modulating the organic semiconductors with or without alkyl chains. This study provides insights for developing a low-cost and environmentally friendly approach for constructing degradable ONeuVSs with sensing, memory, and processing in one device.

环保且可降解的有机神经形态视觉传感器

瞬态电子器件可以帮助消除日益严重的“电子污染”环境问题。然而，它们的应用受到较差的光电性能的严重限制。在这里，通过一步法合成了一种用于有机神经形态视觉传感器（ONeuVSs）的新型可降解聚合物介电材料。获得了 2.74 cm V s 的高迁移率和大于 10 的电流开/关比。此外，我们还获得了出色的光学品质因数，最大光敏度为8.7×10-3，最大探测灵敏度为9.42×10-3琼斯，这是瞬态电子器件中最好的值。 ONeuVS 阵列可以执行静态图像识别，准确率为 92.7%，并具有高通滤波行为。更有趣的是，高性能光学突触和开关功能器件都可以通过调节有或没有烷基链的有机半导体来实现。这项研究为开发一种低成本且环保的方法提供了见解，用于在一个设备中构建具有传感、存储和处理功能的可降解 ONeuVS。
