["Only microstructures are used to improve the sensitivity of iontronic pressure sensors. By modulating the compressive modulus, a breakthrough in the sensitivity of the iontronic pressure sensor is achieved. Furthermore, it allows for programmatic tailoring of sensor performance according to the requirements of different applications. Such a new strategy pushes the sensitivity up to a record-high of 25 548.24 kPa-1 and expands the linear pressure range from 15 to 127 kPa. Additionally, the sensor demonstrates excellent mechanical stability over 10 000 compression-release cycles. Based on this, a well-controlled robotic hand that precisely tracks the pressure behavior inside a balloon to autonomously regulate the gripping angle is developed. This paves the way for the application of iontronic pressure sensors in precise sensing scenarios.","Different from the methods of constructing surface microstructures, this work achieves the design of ultra-high sensitivity capacitive pressure sensors and controllable adjustment of the linear response pressure range by modulating the compressive modulus of the electrodes. Furthermore, active exploration is conducted in applications such as pulse wave monitoring and tactile feedback control of robotic hands. image"]
