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.
