• The iontronic meta-fabric exhibits a "hitting three birds with one stone" property, breaking through the bottleneck that traditional film materials (PDMS) cannot balance comfort and durability.
• The meta-fabrics can be integrated with garments and advanced data analysis systems to manufacture a series of large matrix structure (>40×40, 1600 sensing units) rehabilitation training devices, overcoming the bottleneck of low matrix integration of traditional iontronic devices (<10×10, 100 sensing units).
• The fabric demonstrates outstanding tactile sensing properties, including a wide sensing range (0–300 kPa) and high-resolution tactile perception (50 Pa or 0.058%), enabling precise muscle tension mapping.
• The tunability of piezo-ionic dynamics and programmability of high-resolution imaging modules make this visualization training strategy extendable to various common disease monitoring, paving the way for smart healthcare.
