Kathmandu. Japanese researchers at the University of Tokyo unveiled a revolutionary wearable technology called the Quantum Diamond Sensor in October 2025. The sensor has the ability to detect diseases at the cellular and molecular levels 10 years before symptoms appear.
This technology is based on artificial diamond crystals. It detects the magnetic fields produced by abnormal protein signals from diseased cells as “nuclear whispers”.
Because current tests (MRI and PET) can detect disease only after millions of cells have been damaged, this quantum sensor can detect pancreatic cancer before stage zero or Alzheimer’s disease before cognitive symptoms appear. It is expected to dramatically improve survival rates for diseases such as cancer and nerve damage.
The sensor is worn as a patch of skin. It performs non-invasive scans continuously for 24 hours and analyzes the data with the help of AI algorithms. The technology is currently priced at $800 per scan, but it is expected to drop to $50 per scan within three years.
Experts say this technology will revolutionize diagnosis and usher in a new era of disease prevention and personalized medicine. The sensor will be commercially available in Japan from October 2025.
