Abstract The construction of hydrophobic coatings for flexible sensors is an effective way to improve the stability of sensors-based wearable devices. However, currently available fabrication methods produce coating layers with two simultaneous functions, causing the problem of mutual interference between functions. To independently regulate the two functions, a simple two-step dip-coating process was used in this study to construct independently hydrophobic coatings based on a porous template for sensing purposes. The as-constructed device showed good and independently adjustable hydrophobic (CA = 90°–135°) and sensing performances (GF = 2.5–20). Moreover, the as-obtained strain sensor effectively resisted acid and base corrosion, and displayed a good response to human motion. In sum, the proposed method looks promising for preparing flexible wearable device with decoupled hydrophobic properties and sensing functions.
