Mechanism and Application of Capacitive-Coupled Memristive Behavior Based on a Biomaterial Developed Memristive Device

The memory elements are an indispensable part for many electronic equipment and integrated circuit applications. Nonvolatile resistance random access memory (RRAM) based on the memristive effect is considered to be a promising technology in developing memory devices with low cost and high performance. In this work, to meet the development requirements of green and sustainable electronic devices, a functional electronic device is designed and manufactured by using the earth-abundant resources of wheat flour (WF) as the main component of the dielectric layer. The as-prepared bioelectronic device shows a significant capacitive-coupled memristive effect, which has further been studied by changing the mass mixing ratio of WF and polyvinylidene fluoride (PVDF) under different test temperatures. Ultimately, the working mechanism of the bioelectronic device is explained by a conductive filaments model based on a redox reaction. Therefore, this work not only designs and fabricates a bioelectronic device with the capacitive-coupled memristive effect, but also proposes an artificial implantable application for the development of multifunctional bioelectronic devices.
