AbstractIonic conductive hydrogels are promising candidates for flexible wearable strain sensors and artificial skin. However, achieving high mechanical and sensing performance concurrently remains challenging. Herein, a novel biomineral-reinforced hydrogel composed of polyacrylamide (PAM) and highly stable amorphous calcium carbonate (ACC) is reported. Benefiting from the dual ionic doping strategy (Mg2+ and PO43−), ACC nanoparticles in hybrid hydrogels show a super stable amorphous nature. The resulting mineral hydrogel displays a high stretchability (>1150% strain), a dramatically enhanced fracture toughness (9.57±1.28 vs. 0.91±0.12 kJ m−2), and a desirable linear strain sensitivity. Moreover, the novel mineral hydrogel exhibits high biocompatibility and flame retardance, making it an appealing candidate for wearable device applications.
