Piezoresistive sensors have promising applications in wearable electronics; however, developing multi-functional piezoresistive sensors that possess ultrahigh compressibility and linear working range and could be used in tough environment (e.g., high humidity, corrosive media and low temperatures) remains a challenge. Herein, a flexible electrically conductive polymer foam composite (CPFC) with the lotus leaf inspired microstructure is prepared by anchoring carbon nanotubes (CNTs) onto the skeleton of the polymer foam with the assistance of ultrasonication and simultaneously non-solvent induced phase separation (NIPS). Hemisphere arrays are produced on the skeleton of the polymer foam, while CNTs are decorated on the surface of these arrays, forming conductive network. The obtained superhydrophobic CPFC exhibits excellent anti-corrosive and photothermal conversion performance, making it possible to be used in some harsh environment. When used as the piezoresistive sensor, the CPFC exhibits stable electrical conductivity, extremely high compressibility and linear working range (up to 90%), superb sensing stability and durability (over 2300 cycles). Furthermore, the piezoresistive sensing performance is impervious to the ambient temperature, and the CPFC sensor can work in the temperature from -20 ℃∼80 ℃ with stable sensing signals. Also, the CPFC can detect various human body movements even in the corrosive condition.

压阻传感器在可穿戴电子产品中具有广阔的应用前景。然而，开发具有超高可压缩性和线性工作范围并且可以在恶劣环境（例如高湿度，腐蚀性介质和低温）中使用的多功能压阻传感器仍然是一个挑战。在此，通过在超声作用下同时将碳纳米管（CNT）锚定在聚合物泡沫的骨架上，同时借助非溶剂诱导的相分离（NIPS），制备了具有荷叶启发的微观结构的柔性导电聚合物泡沫复合材料（CPFC）。 。在聚合物泡沫的骨架上产生半球阵列，而在这些阵列的表面上装饰CNT，从而形成导电网络。所获得的超疏水CPFC显示出优异的抗腐蚀和光热转化性能，使得可以在某些恶劣的环境中使用。当用作压阻传感器时，CPFC表现出稳定的导电性，极高的可压缩性和线性工作范围（高达90％），出色的感测稳定性和耐用性（超过2300个循环）。此外，压阻传感性能不受环境温度的影响，CPFC传感器可在-20℃至80℃的温度范围内工作，并具有稳定的传感信号。而且，CPFC即使在腐蚀性条件下也可以检测到各种人体运动。极高的可压缩性和线性工作范围（高达90％），出色的传感稳定性和耐用性（超过2300个循环）。此外，压阻传感性能不受环境温度的影响，CPFC传感器可在-20℃至80℃的温度范围内工作，并具有稳定的传感信号。而且，CPFC即使在腐蚀性条件下也可以检测到各种人体运动。极高的可压缩性和线性工作范围（高达90％），出色的传感稳定性和耐用性（超过2300个循环）。此外，压阻传感性能不受环境温度的影响，CPFC传感器可在-20℃至80℃的温度范围内工作，并具有稳定的传感信号。而且，CPFC即使在腐蚀性条件下也可以检测到各种人体运动。
