除了传统的电性能，在脑启发的神经形态系统中新兴的人工突触设备的材料需要具有类似于生物突触的特性，如突触可塑性。在这项工作中，我们首次研究了天然生物有机材料-蜂蜜的突触特性。将蜂蜜膜夹在Ag和ITO之间，形成类似生物突触的结构。蜂蜜薄膜具有较大的易化指数、较宽的间隔时间范围和较高的动态滤波增益，证明了神经易化是一种重要的突触可塑性。结果表明，蜂蜜是有前途的可再生人工突触装置。
Besides conventional electrical properties, materials for emerging artificial synaptic devices in brain-inspired neuromorphic systems need to have properties analogous to those of biological synapses, such as synaptic plasticity. In this work, we investigated, for the first time, the synaptic properties of a natural bio-organic material – honey. The honey film was sandwiched between Ag and ITO to form a structure resembling biological synapse. Neural facilitation, an essential synaptic plasticity, was demonstrated by honey thin film with a larger facilitation index, wider interval time range and higher dynamic filtering gain than other natural bio-organic materials. The results indicate that honey is promising for renewable artificial synaptic devices.
