Abstract

Biomaterial-based memristors have emerged as a prominent area of research and a hotspot for research on wearable sensors and neuromorphic computing owing to their favorable characteristics of biocompatibility and cost-effectiveness. However, much work is yet to be done to develop biomimetic memristors that are simultaneously flexible and device-stabilized. The study presents a simple approach to preparing flexible memristors using wheat flour (WF) as a functional layer and investigates device stability and synaptic plasticity. The devices can operate stably under continuous voltage scanning for more than 80 weeks, and well emulate biological synaptic functions and synaptic plasticity, such as short-term memory shift to long-term memory and habituation and dehabituation processes. Finally, the mechanisms of the devices' resistive switching and memory transition behaviors were investigated. This work highlights the application of biomaterials in wearable devices and neuromorphic computing, and exemplifies the promise of biomaterials, such as wheat flour, in next-generation environmentally stable and sustainable electronic devices.

基于面粉的柔性记忆器的突触记忆行为研究

生物材料记忆电阻器由于具有良好的生物相容性和成本效益，已成为可穿戴传感器和神经形态计算研究的一个突出研究领域和热点。然而，要开发同时具有柔性和器件稳定性的仿生忆阻器，还有很多工作要做。本研究提出了一种以小麦粉（WF）为功能层制备柔性忆阻器的简单方法，并研究了器件的稳定性和突触可塑性。该装置可以在连续电压扫描下稳定工作80周以上，并能很好地模拟生物突触功能和突触可塑性，如短期记忆向长期记忆的转变以及习惯化和去习惯化过程。最后，研究了器件的阻性开关和记忆跃迁行为的机理。这项工作强调了生物材料在可穿戴设备和神经形态计算中的应用，并举例说明了生物材料（如小麦粉）在下一代环境稳定和可持续电子设备中的应用前景。
