Stack of Bi2Se3/Carbon Films with Pyramid Interface for Dual‑Mode Temperature–Pressure Sensing in Aquatic Environments

Caption

  • A pyramid-interface-structured Bi2Se3 layer was electrochemically constructed on flexible carbon paper, exhibiting excellent hydrophobicity with a contact angle of 143.7°.
  • Dual-mode decoupling of temperature and pressure without cross-interference was achieved using a single material in both air and underwater environments.
  • The sensor maintains stable signal output under prolonged underwater operation, mechanical bending, electromagnetic interference exposure, and even direct flame contact, demonstrating exceptional environmental resilience.
