A small device seen on indian badminton star PV Sindhu’s forehead during the uber Cup 2026 sparked curiosity online. The gadget is called “Temple”, a futuristic wearable that is currently in the testing phase.
🏸 What is the “Temple” device?
The Temple device is an experimental brain-performance wearable developed by a team led by Zomato founder Deepinder Goyal.
It is placed near the temple/forehead area and is designed to:
- Track blood flow in the brain
- Measure cognitive load (mental effort)
- Monitor stress and fatigue levels in real time
👉 It is still a beta (testing) product, not available for public sale yet.
🧬 How does it work?
Unlike fitness bands that track steps or heart rate, this device focuses on brain-related performance signals.
It reportedly:
- Reads subtle physiological signals from the forehead area
- Tracks how hard the brain is working during activity
- Provides data on mental fatigue and concentration levels
Some reports say it aims to give a “deeper view” into athlete performance beyond physical fitness.
🏋️ Why pv sindhu is using it
PV sindhu has been testing the device during training and matches to:
- Understand her mental and physical load
- Improve performance in long matches
- Help optimize recovery and focus
Her team is using it as part of sports-tech experimentation for elite performance tracking.
⚠️ Is it a medical device or commercial product?
- ❌ Not a medical device
- ❌ Not available for public purchase
- ⚙️ Still in experimental/testing phase
- 📊 Data accuracy and effectiveness are still being studied
Experts say it is part of a new wave of neuro-tech wearables, but its real-world impact is not yet proven.
🧠 Why it is trending
The device went viral because:
- It looks unusual (small patch near the eye/forehead)
- Few people had seen brain-monitoring wearables in sports
- PV sindhu using it in an international tournament made it more visible
📌 Final takeaway
The device spotted on PV Sindhu’s forehead is “Temple” — an experimental brain-performance tracker that measures cognitive and physiological signals to study athlete performance. It is still in testing and represents early-stage sports neuro-technology, not a consumer gadget.
