Popis: With the rapid development of artificial intelligence and ever-increasing demand for electronic devices, constructing high-performance flexible pressure sensors is urgently needed. In this study, a novel flexible pressure sensor with superhigh sensitivity and ultrawide detection range is tactfully designed and prepared based on wrinkle-structured MXene film. Due to the unique wrinkle structure, the prepared pressure sensor exhibits outstanding performance including high sensitivity of nearly 860 kPa−1, wide detection range (0.5 Pa ‒ 30 kPa), short response/recover time (40/53 ms) and high stability (11600 cycles). A multi-scale working mechanism is proposed to explain the sensing process. Interestingly, the prepared sensor can easily detect the smallest movement of a millet (2.4 mg) in real time. Based on these advantages, the prepared pressure sensor is expected to show significant potentials in future physiological detection and precision instrument monitoring systems.
