Abstract
Highlights
A self-powered liquid–solid interface ferrofluid-based triboelectric tactile sensor with immediately formed spike-shaped microstructure is proposed.
Due to the high spike microstructure, low Young’s modulus of ferrofluid and efficient solid–liquid interface contact-electrification, an ultrahigh sensitivity of 21.48 kPa−1 for the triboelectric sensors can be achieved.
A strategy for personalized password lock with high security level is demonstrated.
期刊介绍:
Nano-Micro Letters is a peer-reviewed, international, interdisciplinary and open-access journal that focus on science, experiments, engineering, technologies and applications of nano- or microscale structure and system in physics, chemistry, biology, material science, pharmacy and their expanding interfaces with at least one dimension ranging from a few sub-nanometers to a few hundreds of micrometers. Especially, emphasize the bottom-up approach in the length scale from nano to micro since the key for nanotechnology to reach industrial applications is to assemble, to modify, and to control nanostructure in micro scale. The aim is to provide a publishing platform crossing the boundaries, from nano to micro, and from science to technologies.
