Cover Picture: Soft pressure sensors are increasingly used in applications such as wearable technologies, robotics, and health and wellness devices, where the ability to adapt to complex surfaces and the possibility to modulate performance according to specific needs are key requirements. This study presents a soft pressure sensor that combines a magnetic transduction mechanism with hyperelastic materials, where the interplay between material properties and sensor geometry allows the sensing ranges and sensitivity to be adjusted. The sensors cover a sensing range from 6.8 kPa to 77.4 kPa, sensitivity values from 5.1 × 10-2 to 0.4 × 10-2 kPa-1, a recovery time of 0.4 s and low hysteresis, ensuring stable performance over thousands of loading and unloading cycles. The usability of the proposed sensors was investigated in breathing monitoring and finger-tapping detection, highlighting their potential for applications in wearable devices.
