Deepinder Goyal Wears Temple Device on Podcast
Deepinder Goyal, the founder of Zomato, wore a small silver device called Temple on a podcast.
This device is a health-tech gadget that he's been developing to monitor brain blood flow.
It's part of his research into how ageing might be influenced by gravity and neurological factors.
Goyal shared a glimpse of the device on Instagram and explained its purpose on LinkedIn.
The device is designed to be lightweight and worn daily, and it could help track things like memory, focus, stress, and sleep.
While there's no official launch date yet, Goyal's public appearance with the device suggests it's in advanced stages of development.
Some people on social media found the idea funny and made jokes about what the device could be, but Goyal's research is serious and backed by science.
Deepinder Goyal wore a silver device called Temple on the Figuring Out podcast.
Temple is a health-tech device designed to monitor brain blood flow in real-time.
The device is part of Goyal's research into the Gravity Ageing Hypothesis, which suggests gravity reduces blood flow to the brain, leading to ageing.
Goyal first teased Temple on Instagram in early December 2025 and explained its purpose on LinkedIn and Twitter (X).
Temple aims to track cognitive markers like memory, focus, stress, and sleep, and is not yet available for public or commercial use.
