Deepinder Goyal, co-founder of Zomato and Eternal, is transitioning his experimental brain-tracking gadget, Temple, into a consumer product. The latest iteration of the forehead-mounted wearable has been engineered down to less than half the volume of its initial prototype, making it the smallest wearable device currently on the market while simultaneously boosting its processing capability.
The device first captured public interest when Goyal wore a compact metallic prototype clipped to his forehead during an appearance on Raj Shamani’s Figuring Out podcast. Since its initial debut, the health-tech device has been spotted in field testing on elite athletes, including badminton star PV Sindhu.
