Deepinder Goyal Set to Launch Temple Wearable in India
Deepinder Goyal is making a small wearable device called Temple.
It is placed on the side of the head between the forehead and ear.
The device is designed to watch blood flow and oxygen levels in the brain area.
It is still being tested.
Goyal says the newest version is less than half the size of an earlier version.
Some athletes, including PV Sindhu, have been seen wearing it.
Temple is also meant to show a number called Entropy that changes when the body does different activities.
Goyal says the number can change because of sleep, stress, exercise, food, coffee, or meditation.
Zomato founder Deepinder Goyal is preparing to launch the Temple wearable device in India.
Temple is designed to track cerebral blood flow and oxygenation continuously in real time.
The device is currently being tested, and Goyal says its latest version is less than half the previous size.
Athletes including PV Sindhu have recently been seen wearing Temple.
Goyal says Temple measures a temple-region biomarker called Entropy, displayed on an index from 1 to 250.
