5 Key Takeaways

• 1

  A smart contact lens has been developed for non-invasive ocular blood oxygen saturation monitoring.

• 2

  The lens integrates a flexible plasmonic nano-confinement nanowire photodetector for capturing photoplethysmography signals.

• 3

  Initial tests showed approximately 99 percent agreement with a commercial finger-clip oximeter across the SpO₂ range.

• 4

  In rabbit studies, the lens demonstrated SpO₂ changes in parallel with peripheral oximeter readings under varying oxygen conditions.

• 5

  Future research will focus on improving lens stability, wireless operation, and testing in clinically relevant settings.
