Abstract The rational design of high‐performance flexible pressure sensors with both high sensitivity and large workable range attracts great attentions due to the potential applications in wearable electronics human–machine interfaces. Here, carbon black (CB) from diesel soot, an air pollutant produced during incomplete combustion hydrocarbon fuels, is used as active material construct all‐textile sensors. Due unique hierarchical structures surface roughness CB‐coated fabric, sensor exhibits outstanding performances, such (81.61 kPa −1 within 0–10 kPa), extrawide regime (0–100 rapid response relaxation time (6 30 ms, respectively). Based on these superior sensing properties, its practical are demonstrated detecting signals musical sound human physiology, showing for health monitoring electronics.
