Pulse Rate, Pressure and Heart-Condition Monitoring Glasses (US 7376238)

Photonics Spectra
Nov 2008
A pair of health glasses powered by a battery and solar cell has been invented to monitor the heart’s vital signs. LEDs emit light into a human’s temple, and the cells capture light reflected from the pulsing blood. Embedded circuitry cleans and amplifies the signals, which are transmitted to light emitters on the glasses. Heart rhythms and pulse rate are made available to doctors via the Internet. Sensors may be placed on any part of the body.
Applications: Pulse rate monitor; early detection of heart condition.

GLOSSARY
solar cell
A device for converting sunlight into electrical energy, consisting of a sandwich of P-type and N-type semiconducting wafers. A photon with sufficient energy striking the cell can dislodge an electron from an atom near the interface of the two crystal types. Electrons released in this way, collected at an electrode, can constitute an electrical current.
