利用黏菌热特性的混合电路

On hybrid circuits exploiting thermistive properties of slime mould

Xavier Alexis Walter, Ian Horsfield, Richard Mayne, Ioannis A. Ieropoulos, Andrew Adamatzky

摘要:

黏菌多头绒泡菌是一种肉眼可见的单细胞。让黏菌用一个原生质管跨越两个电极:如果管被加热到大约40°C,原生质管的电阻从3 MΩ增加到大约10'000 MΩ。生物体的抵抗力与其环境的温度不成比例,也不相关。因此,黏菌不能被认为是热敏电阻,而是热开关。我们采用多头绒螯蟹的热开关来制作混合电模拟加法器、“与非”门的原型,并将这些门级联成触发器锁存器。在该生物混合计算电路上执行的计算操作具有高重复性、再现性和极低的传播延迟

英文摘要:

Slime mould Physarum polycephalum is a single cell visible by unaided eye. Let the slime mould span two electrodes with a single protoplasmic tube: if the tube is heated to approximately 40°C, the electrical resistance of the protoplasmic tube increases from 3 MΩ to approximatively 10'000 MΩ. The organism's resistance is not proportional nor correlated to the temperature of its environment. Slime mould can therefore not be considered as a thermistor but rather as a thermic switch. We employ the P. polycephalum thermic switch to prototype hybrid electrical analog summator, NAND gates, and cascade the gates into Flip-Flop latch. Computing operations performed on this bio-hybrid computing circuitry feature high repeatability, reproducibility and comparably low propagation delays
