Directional force resolution in flexible sensors is limited
by
material isotropy. Here, we report an anisotropic gelatin-based double-network
hydrogel fabricated via synergistic alignment locking: uniaxial pre-stretching
orients polymer networks and carbon nanotubes, while Hofmeister-mediated
salting-out locks the structure via hydrophobic crosslinking. The
longitudinal orientation provides robust mechanical scaffolding (933
kPa fracture stress), whereas the transverse orientation achieves
exceptional stress sensitivity (45.98 kPa<sup>–1</sup>; 7.6-fold
enhancement). This vectorized response enables mathematical force-vector
calibration mapping (0–90°) via orthogonal multidimensional
sensors. Combined with antifreezing ternary-solvent resilience (−26.2
°C), the system demonstrates real-time robotic control, advancing
directionally aware flexible electronics.
