This paper reports the first successful fabrication of an ITO/silkworm hemolymph/Al bio-memristor using silkworm hemolymph as the active layer. Experiments demonstrate that the silkworm hemolymph bio-memristor is a nonvolatile rewritable bipolar memory device with a current switching ratio exceeding 10. The state of the bio-memristor can be retained for more than 10 seconds and remains stable for at least 500 cycles. Tests of 1/f noise have shown that the resistance switching characteristics of the silkworm hemolymph bio-memristor are related to the formation and breaking of conductive filaments, which result from the migration of oxygen ions and the oxidation and reduction of metal cations in the silkworm hemolymph film. The naturally non-toxic silkworm hemolymph offers advantages for human health, environmental protection, and biocompatibility. The proposed nonvolatile rewritable bio-memristor based on silkworm hemolymph possesses great application potential.
本文报道了首例成功制备的 ITO/家蚕丝液/Al 生物忆阻器，其中家蚕丝液作为活性层。实验表明，家蚕丝液生物忆阻器是一种具有超过 10 倍电流开关比的非易失性可重写双极存储器。该生物忆阻器的状态可以保持超过 10 秒，并且至少稳定 500 个循环。1/f 噪声测试表明，家蚕丝液生物忆阻器的电阻开关特性与导电线的形成和断裂有关，这是由于丝液薄膜中的氧离子迁移以及金属阳离子的氧化和还原所致。天然无毒的家蚕丝液在人体健康、环境保护和生物兼容性方面具有优势。所提出的基于家蚕丝液的非易失性可重写生物忆阻器具有巨大的应用潜力。
