黏菌型忆阻器

Slime Mould Memristors

Ella Gale, Andrew Adamatzky, Ben de Lacy Costello

摘要:

在实验室实验中,我们证明,原生质管的无细胞黏菌\emph{Physarum polycephalum}显示电流与电压曲线与忆阻系统一致,该效果是由于活原生质的模具。这补充了以前对其他生命系统(人类皮肤和血液)的记忆特性的发现,并有助于自生长生物电子电路的发展。独特的不对称$V$ - $I$曲线,这是偶尔观察到的内部电流是在相同的数量级的驱动电流,是很好地模拟了有源忆阻器的概念。

英文摘要:

In laboratory experiments we demonstrate that protoplasmic tubes of acellular slime mould \emph{Physarum polycephalum} show current versus voltage profiles consistent with memristive systems and that the effect is due to the living protoplasm of the mould. This complements previous findings on memristive properties of other living systems (human skin and blood) and contributes to development of self-growing bio-electronic circuits. Distinctive asymmetric $V$-$I$ curves which were occasionally observed when the internal current is on the same order as the driven current, are well-modelled by the concept of active memristors.
