Memristive devices are gaining importance in the semiconductor industry for applications in information storage, artificial intelligence cryptography and telecommunication. Memristive devices fabricated by solution-processing methods can be integrated into a wide variety of large-area substrates, which has motivated their use in applications requiring flexible, stretchable, transparent and biocompatible devices. Several studies on solution-processed memristors have claimed excellent electrical performance; however, in many cases such claims are based on scarce measurements conducted on only one device, using unreliable testing protocols or using device structures that are too large for the target applications. Understanding the reliability of a memristive structure is important to avoid hyped expectations, attract potential investments in such technology, and realistically understand its potential impact on society and on the market. In this Perspective, we analyse which solution-processed memristors have so far exhibited the highest and most reliable electronic performance, irrespective of the type of material used and the application targeted. For that group of memristors, we also discuss the switching mechanism and potential applications, as well as possible improvements in terms of device technology. We describe the outlook of this field with aims of increasing the impact and technology readiness of solution-processed memristors.

忆阻器件在半导体行业中的信息存储、人工智能密码学和电信应用中变得越来越重要。通过溶液加工方法制造的忆阻器件可以集成到各种大面积基板中，这促使它们在需要柔性、可拉伸、透明和生物相容性器件的应用中得到应用。多项关于溶液处理忆阻器的研究都声称具有出色的电气性能。然而，在许多情况下，此类声明基于仅在一台设备上进行的稀缺测量，使用不可靠的测试协议或使用对于目标应用来说太大的设备结构。了解忆阻结构的可靠性对于避免炒作期望、吸引对此类技术的潜在投资以及切实了解其对社会和市场的潜在影响非常重要。在本视角中，我们分析了迄今为止哪些溶液处理的忆阻器表现出最高和最可靠的电子性能，无论使用的材料类型和目标应用如何。对于这组忆阻器，我们还讨论了开关机制和潜在应用，以及器件技术方面可能的改进。我们描述了该领域的前景，旨在提高溶液处理忆阻器的影响和技术准备度。
