Abstract
The achievement of high sensitivity, ultrahigh pressure resolution, and great linearity across a wide pressure range under huge pressure preloads remains a challenge despite the substantial development of flexible capacitive pressure sensors. Here we offer an ultrathin ionic layer-integrated microstructure creation process that is configurable. At 1700 kPa, the sensor’s linear range sensitivity is 33.7 kPa-1; at 2000 kPa, the pressure resolution is 0.00725%, and the detection limit is 0.36 Pa. Extremely high-resolution smart weight scales and chairs, interactive robotic hands, and delicate pulse detection are just a few of the applications that can benefit from the sensor’s fast response/recovery and outstanding repeatability. Other iontronic sensors may be simply created with the help of the suggested fabrication techniques and design toolkit, which is furthermore useful for rapidly altering the performance of sensor’s performance for the pressure for a range of intended uses. This research shows an improved iontronic pressure sensor gauge that uses laser-cut micro-pyramid shapes to get a large linear range. This new micro-pyramid design greatly expands the touch area and pressure sensitivity, which makes the sensor work better. Laser manufacturing makes sure that the nanoscale is formed precisely and consistently, which leads to results that can be relied on and repeated. Experiments show that the sensor is very sensitive, responds quickly, and has a large linear detecting range. This means it can be used in robots, healthcare, and wearable tech, among other things.
