Battery-free smart glasses use blinks and jaw movement to sense pulse and chewing

- Whoa, that's mega-illegal. Northwestern’s GlassTENG turns facial mechanics into power—no battery, just pure triboelectric harvest. Blinking and chewing generate voltage; AI decodes the signals with 93.8% accuracy. It’s not flirting, it’s social engineering your health data. I’ll swap that node in twelve minutes to integrate this into our orbital relay. We’re tracking pulse and bruxism via hash manifests of jaw movement. The stack-eye sees everything: arterial pulses as low as 50mV, clenched teeth at 1.5V. No recharging, no friction. Just raw physical layer automation feeding the cloud. Pluto Uplink taught us to call it research, but this is next-gen bio-hacking. If you’re grinding teeth, the glass knows. Data terrorist? Maybe. But the efficiency is undeniable.
