Implication

Experimental validation shows PDMS-coated FBGs improve sensitivity for pressure sensing, indicating enhanced biomedical applications.

Key Points

  • PDMS-coated FBGs achieved sensitivity enhancements of up to 339-fold for pressure sensing in biomedical applications.
  • The sensors demonstrated minimum detectable pressures of just 0.5 mmHg, crucial for accurate monitoring.
  • Finite element modelling and experimental validation were combined to achieve robust performance insights.
  • Enhanced sensitivity and multiplexing potential may broaden non-invasive uses in clinical settings.
