A High Compressibility Pressure—Sensitive Structure Based on CB@PU Yarn Network

A High Compressibility Pressure—Sensitive Structure Based on CB@PU Yarn Network

In this work, a piezoresistive sensor structure based on carbon black (CB)@polyurethane (PU) yarn material was developed. Specifically, CB@PU yarn was constructed by the polymer-mediated water-based electrostatic deposition method. The distribution of the yarn was artificially controlled to fabricat...
