  • Description:
    Despite the extensive developments of flexible capacitive pressure sensors, it is still elusive to simultaneously achieve excellent linearity over a broad pressure range, high sensitivity, and ultrahigh pressure resolution under large pressure preloads. Here, we present a programmable fabrication method for microstructures to integrate an ultrathin ionic layer. The resulting optimized sensor exhibits a sensitivity of 33.7 kPa-1 over a linear range of 1700 kPa, a detection limit of 0.36 Pa, and a pressure resolution of 0.00725% under the pressure of 2000 kPa. Taken together with rapid response/recovery and excellent repeatability, the sensor is applied to subtle pulse detection, interactive robotic hand, and ultrahigh-resolution smart weight scale/chair. The proposed fabrication approaches and design toolkit from this work can also be leveraged to easily tune the pressure sensor performance for varying target applications and open up opportunities to create other iontronic sensors. Author correction https://doi.org/10.1038/s41467-023-39675-z: The original version of this Article contained an error in Fig. 2g, in which the legend of curve 'GPML700 20 wt%' was incorrectly swapped with 'GPML700 50 wt%', and 'GPML500 20 wt%' was incorrectly swapped with 'GPML500 50 wt%'. The original version of this Article omitted that '(3-Aminopropyl)triethoxysilane (APTES)' was obtained from Sigma-Aldrich. This has now been included in the 'Materials and chemicals' subsection of the 'Methods' section. Finally, the original version of the Supplementary Information contained errors or misplaced information in Supplementary Tables 2, 4, 6. [Description provided by NIOSH]
