Piezoresistive Pressure Sensor Based on Synergistical Innerconnect Polyvinyl Alcohol Nanowires/Wrinkled Graphene Film

Abstract: Piezoresistive sensor is a promising pressure sensor due to its attractive advantages including uncomplicated signal collection, simple manufacture, economical and practical characteristics. Here, a flexible and highly sensitive pressure sensor based on wrinkled graphene film (WGF)/innerconnected polyvinyl alcohol (PVA) nanowires/interdigital electrodes is fabricated. Due to the synergistic effect between WGF and innerconnected PVA nanowires, the as-prepared pressure sensor realizes a high sensitivity of 28.34… Show more

“…In the past decade, considerable progress has been made on wearable electronic devices including artificial electronic skins (E‐skins) 1–6. Owing to the capability to transduce physical signals (e.g., pressure, strain, temperature, perspiration, and other stimuli) into electric signals,1–10 E‐skins have massive potentials in the applications for human motion detection,11,12 health monitoring,3,13–15 bionics,4,8 artificial intelligence,14b and so on. As a fundamental part of E‐skins, pressure sensors with a high sensitivity and a low detection limit (DL) are highly desired1–4,11,16,17 because these two of the most important performances are intimately related to the applications.…”

“…Among them, the pressure/strain sensors based on the piezoresistive effect are widely prepared for physical physiological information detection due to their simple device structure and large measuring range. For the 2D materials of graphene, rGO, and MXenes, they are widely used in the flexible piezoresistive pressure or strain sensor due to their high conductivity and excellent mechanical properties . To fabricate high‐performance mechanical sensors, highly conductive 2D materials with microflakes would be beneficial to the enhancement of their key parameters such as sensitivity, measuring range, detection limit, and so on.…”

“…[ 11–15 ] Among the different kinds of pressure sensors, piezoresistive pressure sensor demonstrates great application potential because of its fast response speed, simple structure, economical fabrication process and great stability. [ 16–20 ] Improvement of sensitivity of pressure sensors is critical for the high precision and ultrasensitive pressure detection, [ 21–25 ] which is however a challenging task because the key effect of device configuration on the sensitivity is always neglected.…”
