生物体使用依赖于控制离子的自组装结构来形成传感器，并在不使用大规模集成半导体电路的情况下收集、处理和传输信息。[1]开发电子设备的灵感来自这样的策略，即离子运动和电化学反应，可以导致新的功能。我们在这里展示了如何耦合的电气和电化学性能可以被设计为重现一个施密特触发器在一个单一的元素的特性。施密特触发器是一种用于噪声滤波和模数转换器的电路，[2]它可以用作神经形态电子系统的基本元件。[3，4]为了在一个器件元件中形成简单的施密特触发器，我们将离子液体门控金属氧化物半导体和普通生物分子的电化学反应耦合，以通过化学机制提供稳定的操作。这种耦合是一种化学自修复机制，因为它是可逆的，我们希望这种机制也可以扩展到其他材料。我们相信，新的设备，使用离子动力学的灵感来自活的有机体可能会导致高度集成的电子电路的智能传感器和无处不在的计算应用。[五]《中国日报》
Living organisms use self-assembled structures that rely on controlling ions to form sensors and collect, process, and transmit information without using large scale integrated semiconducting circuits.[1] Developing electronic devices inspired by such strategies, ie, ion motion and electrochemical reactions, can lead to novel functionality. We show here how coupling of electrical and electrochemical properties can be designed to reproduce the characteristics of a Schmitt trigger in a single element. The Schmitt trigger is a circuit used for noise filtering and analog-to-digital converters,[2] and it can be used as a basic element of neuromorphic electronic systems.[3, 4] To form a simple Schmitt trigger in one device element, we couple electrochemical reactions of an ionic liquid gated metal oxide semiconductor and a common biomolecule to provide stable operation through a chemical mechanism. This coupling is a type of a chemical self-healing mechanism because of its reversibility, and we expect that such a mechanism can also be extended to other materials as well. We believe that new devices that use ion kinetics inspired by living organisms may lead to highly integrated electronic circuits for smart sensor and ubiquitous computing applications.[5]
