Northwestern glasses run sensors on blinks and pulse
Researchers built glasses whose sensors make their own power from facial movement. They spot jaw clenching with 93.8% overall accuracy in a 20-person test.
Scientists made glasses that make their own tiny bit of power when you blink or clench your jaw. That power runs the sensors. It is still a lab project.

Your call: hype or real?
Real = it will matter in daily use. Hype = louder than it is. One vote, and it can’t be changed.
Our view and readers’ views are opinions, not statements of fact about a product.
Why it matters
Sensors that power themselves could mean smart glasses with fewer batteries to charge.
Worth a look: glasses that run on your own movement.
The details
- Three thin sensors sit at the nose bridge, temple and ear, and make small voltages when the face moves.
- The three sensors together draw 4.1 microwatts and send data to a phone by Bluetooth.
- They detect blinking, eyebrow raises, jaw clenching and teeth tapping.
- In a study of 20 people, overall accuracy was 93.8%, with 99% for teeth tapping.
- It is a research prototype; no product plans were mentioned.
