Artificial ionic nanochannels with light perception capabilities hold promise for creating ionic devices. Nevertheless, most research primarily focuses on regulating single nanochannels, leaving the cumulative effect of numerous nanochannels and their integration underexplored. We herein develop a biomimetic photoreceptor based on photoresponsive highly aligned nanochannels (pHANCs), which exhibit uniform channel heights, phototunable surface properties, and excellent compatibility with microfabrication techniques, enabling the scalable fabrication and integration into functional ionic devices. These pHANCs demonstrate exceptional ion selectivity and permeability due to the high surface charges and well-ordered conduits, resulting in outstanding energy harvesting from concentration gradients. Large-scale fabrication of pHANCs has been successfully realized, wherein hundreds of biomimetic photoreceptors produce an ultrahigh voltage over 76 volts, which has not been achieved previously. In addition, we demonstrate that the biomimetic photoreceptor can be further upscaled to be a self-powered ionic image sensor, capable of sensing and decoding incident light information.

用于自供电离子器件的光响应高度对齐纳米通道的可扩展集成


具有光感知能力的人工离子纳米通道有望创建离子器件。然而，大多数研究主要集中在调节单个纳米通道上，而许多纳米通道的累积效应及其整合尚未得到充分探索。我们在这里开发了一种基于光响应高度对齐纳米通道 （pHANC） 的仿生光感受器，它表现出均匀的通道高度、光可调表面特性以及与微纳加工技术的出色兼容性，能够进行可扩展的制造和集成到功能性离子器件中。由于高表面电荷和井然有序的导管，这些 pHANC 表现出卓越的离子选择性和渗透性，从而从浓度梯度中收集出色的能量。pHANCs 的大规模制造已经成功实现，其中数百个仿生光感受器产生超过 76 伏的超高电压，这在以前是无法实现的。此外，我们还证明，仿生光感受器可以进一步放大为自供电离子图像传感器，能够感应和解码入射光信息。
