Overview
- PV Sindhu was seen wearing Temple on the side of her forehead while competing at the BWF World Championships in New Delhi this week, confirming athlete testing in live matches.
- Temple is a small clip‑on device led by Deepinder Goyal's team that uses light‑based sensors and AI to monitor cerebral blood flow, oxygenation, cognitive load and a proprietary 'entropy' metric.
- The device remains experimental and unavailable for general sale, with an early‑access program running and developers saying a wider launch could come in the coming months.
- Sindhu has tested Temple in training and provided feedback to the developers, and her use in competition is intended to collect real‑world data that could inform training, recovery and focus ahead of events such as the 2028 Olympics.
- Temple’s makers stress it is not a medical diagnostic and plan peer‑reviewed studies to validate claims, a necessary step before teams or consumers rely on its brain‑based metrics for performance decisions.
