类蛋白是在水溶液中膨胀成微球的热蛋白。类蛋白的集合产生类似于神经元的电尖峰活动。我们介绍了一种利用计时电流法在类蛋白微球集成中实现逻辑门的新方法。计时安培法是一种向类蛋白微球施加电压脉冲并测量其电流响应的技术。我们观察到，类蛋白表现出与各种逻辑输出相一致的独特电流模式。我们确定了四种类型的逻辑门：AND， OR， XOR和NAND。这些门是由类蛋白微球的电流反应决定的。此外，我们证明了类蛋白微球具有随时间改变其电流响应的能力，这受其先前暴露于电压的影响。这表明它们具有学习能力，能够适应环境。我们的研究展示了类蛋白微球通过其固有的电学特性进行逻辑运算和计算的能力。
Proteinoids are thermal proteins which swell into microspheres in aqueous solution. Ensembles of proteinoids produce electrical spiking activity similar to that of neurons. We introduce a novel method for implementing logical gates in the ensembles of proteinoid microspheres using chronoamperometry. Chronoamperometry is a technique that involves applying a voltage pulse to proteinoid microspheres and measuring their current response. We have observed that proteinoids exhibit distinct current patterns that align with various logical outputs. We identify four types of logical gates: AND, OR, XOR, and NAND. These gates are determined by the current response of proteinoid microspheres. Additionally, we demonstrate that proteinoid microspheres have the ability to modify their current response over time, which is influenced by their previous exposure to voltage. This indicates that they possess a capacity for learning and are capable of adapting to their environment. Our research showcases the ability of proteinoid microspheres to perform logical operations and computations through their inherent electrical properties.
