For computer scientists是, creationofneuromorphicsystems-thoseinspiredbyandmodeledafterthewayneuronsinthehumanbrainarestructured-hasbeenalongstans l .科建立模仿神经形态的系统仍然是多年的目标,这个想法来源于人类脑内神经元的包含方式,被模仿。Now,inasignificantsteptowardthedevelopmentofneuromorphictechnologies,agroupofresearchersibmsresearchlaboratoryinzurichaveans 作为神经形态技术发展的最重要的一步,位于苏黎世的IBM实验室,研究小组宣布他们发明了已经运营中的人工神经元。The invention, describedinapaperpublishedinthejournalnaturenanotechnology, consistsofasmallsquareofgermaniumantimonytellurideheldbetweentwoelectrodes.germaniumantimonytelluride是acommoningredientinops iswhatisknownasphase-change material.thismeansitcanchangeitsphasefromanamorphousinsulatortoacrystallineconductorwhenhit tronger tinglikeboth,a resister and capacitor,and mimicking,to a certain extent,thebehaviorofbiologicalneuronslipidbilayermembrane .本发明者本发明者在两个电极之间含有较小的锗锑碲。

锗锑碲是制作光盘的罕见材料,也就是所谓的热力学材料。这意味着著遇到足够强的电子脉冲时,需要从有形绝缘体变化为结晶状态导体,其工作原理在电阻器和电容器中都可见,可能是模仿生物神经脂质双分子层的特性。
