Our research is aimed at gaining a better understanding of the electronic properties of organisms in order to engineer novel bioelectronic systems and computing architectures based on biology. This specific paper focuses on harnessing the unicellular slime mold Physarum polycephalum to develop bio-memristors (or biological memristors) and bio-computing devices. The memristor is a resistor that possesses memory. It is the 4th fundamental passive circuit element (the other three are the resistor, the capacitor, and the inductor), which is paving the way for the design of new kinds of computing systems; e.g., computers that might relinquish the distinction between storage and a central processing unit. When applied with an AC voltage, the current vs. voltage characteristic of a memristor is a pinched hysteresis loop. It has been shown that P. polycephalum produces pinched hysteresis loops under AC voltages and displays adaptive behavior that is comparable with the functioning of a memristor. This paper presents the method that we developed for implementing bio-memristors with P. polycephalum and introduces the development of a receptacle to culture the organism, which facilitates its deployment as an electronic circuit component. Our method has proven to decrease growth time, increase component lifespan, and standardize electrical observations.
我们的研究旨在更好地理解生物体的电子特性，以便设计基于生物学的新型生物电子系统和计算架构。这篇特定的论文专注于利用单细胞黏菌多头绒泡菌来开发生物忆阻器（或生物忆阻器）和生物计算设备。忆阻器是一种具有记忆功能的电阻器。它是第四个基本无源电路元件（其他三个是电阻器、电容器和电感器），为新型计算系统的设计铺平了道路；例如，可能消除存储和中央处理器之间区别的计算机。当施加交流电压时，忆阻器的电流与电压特性是一个收缩的磁滞回线。已经表明，多头绒泡菌在交流电压下会产生收缩的磁滞回线，并表现出与忆阻器功能相当的自适应行为。本文介绍了我们开发的用多头绒泡菌实现生物忆阻器的方法，并介绍了一种用于培养该生物体的容器的开发，这有助于将其作为电子电路组件进行部署。我们的方法已被证明可以缩短生长时间、延长组件寿命并使电观测标准化。
