A viral buzz has emerged around Indian badminton star PV Sindhu after she was seen wearing a small experimental wearable device on her forehead during a recent match at the Uber Cup in Denmark. The device has been linked to Zomato founder Deepinder Goyal’s ongoing experimental project known as “Temple,” which has sparked widespread curiosity in sports and tech circles.
The wearable, placed near Sindhu’s temple area, is a lightweight sensor reportedly designed to track real-time physiological data such as blood flow to the brain and cognitive load. It is part of a broader research initiative associated with Goyal’s private experimentation in longevity and human performance monitoring. The device has not been officially commercialised and remains in a testing phase.
According to reports, Sindhu has been using the device in training sessions before deploying it in a competitive match situation for the first time. The move is being viewed as part of an ongoing attempt to integrate advanced biometric tracking into elite sports performance, allowing athletes and their support teams to better understand physical and cognitive stress during play.

The technology behind the “Temple” device is still experimental and has not been validated as a medical-grade diagnostic tool. It is primarily aimed at collecting performance-related data rather than replacing established medical or sports science equipment. Experts have noted that while such wearables represent an emerging trend in sports analytics, their real-world effectiveness at elite competition level is still under evaluation.
PV Sindhu’s use of the device has triggered discussion about the growing intersection of sports and wearable technology, especially in disciplines where marginal gains in focus, endurance, and recovery can significantly impact results. However, the project remains in a research phase, and no official conclusions have been drawn regarding its long-term impact on athletic performance or injury prevention.
