A flexible and highly sensitive pressure sensor based on three-dimensional electrospun carbon nanofibers.

ABSTRACT: High-performance flexible pressure sensors with high sensitivity are important components of the systems for healthcare monitoring, human-machine interaction, and electronic skin. Herein, a flexible and highly sensitive pressure sensor composed of ferrosoferric oxide (Fe₃O₄)/carbon nanofibers (FeOCN) was fabricated using three-dimensional electrospinning and further heat treatment methods. The obtained pressure sensor demonstrates a wide working range (0-4.9 kPa) and a high sensitivity of 0.545 kPa^-1 as well as an ultralow detection limit of 6 Pa. Additionally, the pressure sensor exhibits a rapid response time, good stability, high hydrophobicity, and excellent flexibility. These merits endow the pressure sensor with the ability to precisely detect wrist p
