The recyclable, self-healing and easily-degradable transient electronic technology has aroused tremendous attention in flexible electronic products. However, integrating the above advantages into one single flexible electronic device is still a huge challenge. Herein, we demonstrate a flexible and recyclable bio-based memory device using fish colloid as the resistive switching layer on a polyimine substrate, which affords reliable mechanical and electrical properties under repetitive conformal deformation operation. This flexible bio-based memory device presents potential analog behaviors including memory characteristics and excitatory current response, which undergoes incremental potentiation in conductance under successive electrical pulses. Moreover, this device is expected to greatly alleviate the environmental problems caused by electronic waste. It can be decomposed rapidly in water and well recycled, which is a promising candidate for transient memories and information security. We believe that this study can provide new possibilities to the field of high-performance transient electronics and flexible resistive memory devices.
可回收、自修复和易降解的瞬态电子技术在柔性电子产品中引起了极大的关注。然而，将上述优点集成到单个柔性电子设备中仍然是一个巨大的挑战。在这里，我们展示了一种基于鱼胶体的可回收和柔性生物基阻变存储器，该存储器在聚酰亚胺基底上作为阻变层，在重复的保形变形操作下提供可靠的机械和电气性能。这种柔性生物基忆阻器呈现出潜在的模拟行为，包括忆阻特性和兴奋电流响应，在连续电脉冲下其电导呈递增增强。此外，该器件有望极大地缓解电子废物带来的环境问题。它可以在水中迅速分解并很好地回收利用，是一种很有前途的瞬态存储器和信息安全候选材料。我们相信，这项研究为高性能瞬态电子学和柔性阻变存储器件领域提供了新的可能性。
