5 Key Takeaways

• 1

  A new eye-tracking system harnesses energy from blinking, using a triboelectric nanogenerator for power without external sources.

• 2

  The device operates in complete darkness, eliminating safety concerns associated with infrared illumination in traditional eye tracking.

• 3

  Experimental results show the system can detect eye movements with 99% accuracy, even in low-light environments.

• 4

  Material choice, including polydimethylsiloxane, ensures optical transparency, durability, and biocompatibility without ocular irritation.

• 5

  This innovative approach could revolutionize wearable ophthalmic devices by utilizing the natural reflex of blinking for power.
