Shape memory hydrogels have promising applications in a wide variety of fields. Here we report the facile fabrication novel type shape physically cross-linked with both stronger and weaker hydrogen bonding (H-bonding). Strong multiple H-bonding formed between poly(vinyl alcohol) (PVA) tannic acid (TA) leads to their coagulation when they are mixed at an elevated temperature easy gelation room temperature. The amorphous structure strong endow PVA-TA excellent mechanical properties, as...

Abstract Recently, flexible pressure sensors (FPSs) have attracted intensive attention owing to their ability mimic and function as electronic skin. Some are exploited with a biological structure dielectric layer for high sensitivity detection. However, traditional bionic structures usually suffer from limited range high‐pressure scenes due hysteresis in the medium range.
