Graphene Aerogel‑Based Flexible Pressure Sensor for Physiological Signal Detection and Human–Machine Interaction

Caption

  • Reduced graphene oxide aerogel (rGOA) was prepared via freeze-casting, featuring an ultra-light density (10 mg cm−3) and a unique anisotropic structure, which bring advantages to pressure sensing.
  • The rGOA-based pressure sensor exhibits a sensitivity as high as 698.96 kPa−1, a detection range as wide as 100 kPa, and a cyclic stability of over 20,000 cycles.
  • The integration of rGOA with manipulators enables teleoperation, stable grasping of fragile objects with force-feedback and 100% accuracy in food recognition.
