A Flexible, Highly Accurate, and Stable Pressure Sensor with Anti‐Interference from Temperature, Sweat, and Humidity

The highly accurate and stable pressure sensors with anti-interference from varying sensing environments (temperature humidity) are essential a challenge in practical applications. However, real-time electrical resistance fluctuation or even inaccuracy widely existed due to the sensibility of conductive materials towards temperatures, humidity, sweat circumstance. Here, for first time, hydrophobic, non-fluoride, titanium dioxide nanoparticle (TiO2-ODI) modified carbon nanotube (CNT)/carbon black (CB) introduced achieve temperature, droplets, humidity. near-zero temperature coefficient (near-ZTC) effect (≈ −10 70 °C). moisture benefits effective isolation hydrophobic TiO2-ODI layer. Meanwhile, TiO2-ODI/CNT/CB obtain favorable sensitivity 1.57 kPa−1, fast response time 20 ms, negligible hysteresis ratio 1.9%, prominent air permeability, facile scalable strategy. Hence, feasible accurately stably under by efficiently suppressing interferences high sweat.
