A flexible pressure sensor array provides more information than a single as electronic skin, and independently definable sensitivities of sensing pixels enable accurate measurements. However, the reported approaches, either changing mold for dielectric layer or tuning properties, overcomplicate manufacturing process devices. Here, we present with photo-patterned sensitivity, which is realized through synergistic creation photo-defined mechanical properties interfacial capacitive mechanism. Via this design, sensitivity each pixel can be over range ∼70 times magnitude. Additionally, created first wearable measurement unit ionic array. The sensitivity-photo-patternable fulfill open need mapping distribution broad magnitude, such plantar pressure.
