Abstract

Flexible pressure sensors may be used in electronic skin (e-skin), artificial intelligence devices, and disease diagnosis, which require a large response range and high sensitivity. An appropriate design of the structure of the active layer can help effectively solve this problem. Herein, we aim at developing a wearable pressure sensor using the MXene/ZIF-67/polyacrylonitrile (PAN) nanofiber film, fabricated by electrospinning technology. Owing to the rough structure and three-dimensional network architecture, the MXene/ZIF-67/PAN film-based device displays a broad working range (0–100 kPa), good sensitivity (62.8 kPa–1), robust mechanical stability (over 10,000 cycles), and fast response/recovery time (10/8 ms). Moreover, the fabricated pressure sensors can be used to detect and differentiate between different body motion information, including elbow bending, finger movements, and wrist pulses. Overall, this design of a rough three-dimensional conductive network structure shows potential in the field of wearable electronics and medical devices.
