近年来无线传感器网络和物联网的出现,促进了人机交互的发展。人机交互则离不开制作可穿戴或可附着的电子器件,这些电子器件对延展性,生物相容性和透明度都有较高的要求。针对这一问题,近日在《自然-通讯》上发表的一篇文章Transparent and attachable ionic communicators based on self-cleanable triboelectric nanogenerators做了相关研究。

由于重量和体积的限制,可穿戴设备应该高效节能,或者甚至可以自供电。文中,来自国立首尔大学的Jeong-Yun Sun及同事介绍了几种实用的方法,用摩擦纳米发电机来制作稳定的自清洁透明附着型离子通讯器。

这种通讯器表层柔软,健康无害,因此可以轻易贴敷在人类皮肤上,实现人和机器之间的实时通信。由于具有自清洁效应,通讯器的表面功能化可以在不影响透明度的情况下,通过(1,1,2,2-十七氟癸基)三氯甲硅烷来提升灵敏度,并使通讯器保持稳定的电学与光学性质。该研究对于可附着型离子器件,自供电型传感器网络,及生物力学监测系统的发展,都具有潜在的应用价值。

摘要:Human–machine interfaces have benefited from the advent of wireless sensor networks and the internet of things, but rely on wearable/attachable electronics exhibiting stretchability, biocompatibility, and transmittance. Limited by weight and volume, wearable devices should be energy efficient and even self-powered. Here, we report practical approaches for obtaining a stably self-cleanable, transparent and attachable ionic communicator based on triboelectric nanogenerators. The communicator can be easily applied on human skin due to softness and chemically anchored robust layers. It functions as a means of real-time communication between humans and machines. Surface functionalization on the communicator by (heptadecafluoro-1,1,2,2-tetrahydrodecyl)trichlorosilane improves sensitivity and makes the communicator electrically and optically stable due to the self-cleaning effect without sacrificing transmittance. This research may benefit the potential development of attachable ionics, self-powered sensor networks, and monitoring systems for biomechanical motion.
