“…The development of superhydrophobic flexible pressure sensors has received a lot of attention recently. − Wang et al combined fluorinated poly(dimethylsiloxane) with multi-walled carbon nanotubes (MWCNTs) to produce a superhydrophobic strain sensor, which retained superhydrophobicity after 1000% stretching, 10000 stretch cycles, hand-rub, tape-peeling, and high-speed water impact . Poly(dimethylsiloxane) (PDMS) exhibits apparent advantages in fabricating superhydrophobic functional materials due to the high wear resistance and low surface energy. − The superhydrophobic flexible pressure sensor is prepared using PDMS as a binder to enhance the adhesion between hydrophobic materials and substrates. , For instance, Hu et al adopted spray coating to prepare a CB conducting layer atop a PDMS flexible layer, leading to a strain sensor with relatively high GF (up to 67.2), and high tensile strain (up to 100%) . However, developing superhydrophobic pressure sensors with flexibility, high sensitivity, exceptional reliability, durability, and suitability for underwater human motion signal monitoring remains a challenge.…”
