New Delhi: A small metallic-coloured gadget affixed to the temple of Zomato founder and Eternal CEO Deepinder Goyal grabbed widespread attention on social media this week after he appeared wearing it on the Figuring Out podcast hosted by Raj Shamani. The device triggered a flurry of online speculation — with many viewers joking that it looked like chewing gum or an “external SSD” — before its true purpose was clarified.
The clip-on device, officially called Temple, is an experimental wearable designed to track blood flow in the brain in real time.
Unlike typical clinical tools used intermittently in research settings, Temple aims to collect continuous measurements of cerebral blood flow, potentially offering new insights into neurological health and the ageing process.
Goyal has been testing the device himself for around a year, and its development is linked to his personal research initiative exploring what he calls the Gravity Ageing Hypothesis — a theory about how gravity’s pull over a lifetime could affect blood circulation in the brain and influence ageing, reported India Today.
The device’s appearance during the podcast sparked widespread curiosity and a wave of memes, but those familiar with Goyal’s work on Temple emphasise that it is not a consumer product and is still in the experimental phase under development.
Temple’s development is associated with Continue Research, a research initiative funded by Goyal’s own capital investment, reported to be in the range of about $25 million.
Wearable sensors capable of tracking cerebral health markers are an active area of scientific research, but tools with Temple’s capabilities remain largely confined to controlled studies rather than broad public use, experts said, as quoted by India Today.
