Flexible strain or pressure sensors have potential applications in electronic skin, healthcare, etc. It remains a challenge to explore multifunctional that possess excellent water repellent and heating performance hence can be used harsh environments such as high moisture low-temperature conditions. Here, self-derived superhydrophobic polymer composite foam is prepared by adsorption of the Ag precursor tetrahydrofuran (THF) onto rubber sponge followed reduction Ag+ nanoparticles (AgNPs). During hydrazine solution, swollen THF partially precipitated based on nonsolvent-induced phase separation (NIPS). The NIPS creates porous structure surface thus roughness, contributing material superhydrophobicity. wrapping AgNPs could enhance interaction between individual AgNPs. obtained conductive possesses Joule photothermal both sensor. sensor good reliability durability applied real-time monitoring human body movements.
