The fields of electronic skin, man-machine interaction, and health monitoring require flexible pressure sensors with great sensitivity. However, most microstructure designs utilized to fabricate high-performance pressure sensors require complex preparation processes. Here, MXene/polyaniline (PANI) foam with 3D porous structure is achieved by using a steam-induced foaming method. Based on the structure, a flexible piezoresistive sensor is fabricated. It exhibits high sensitivity (690.91 kPa ), rapid response, and recovery times (106/95 ms) and outstanding fatigue resistance properties (10 000 cycles). The MXene/PANI foam-based pressure sensor can swiftly detect minor pressure and be further used for human activity and health monitoring.
电子皮肤、人机交互和健康监测领域需要具有高灵敏度的柔性压力传感器。然而，大多数用于制造高性能压力传感器的微结构设计都需要复杂的制备工艺。在此，通过蒸汽诱导发泡法制备了具有三维多孔结构的MXene/聚苯胺（PANI）泡沫。基于该结构，制备了一种柔性压阻传感器。它具有高灵敏度（690.91 kPa）、快速响应和恢复时间（106/95 ms）以及出色的抗疲劳性能（10000次循环）。基于MXene/PANI泡沫的压力传感器能够快速检测微小压力，并可进一步用于人体活动和健康监测。
