- Researchers developed a 'negative luminescence' system for hidden data transmission.
- The system makes signals blend into natural heat radiation, making them invisible to observers.
- Only receivers with specific equipment can detect the hidden messages.
- This method offers high security, making signals nearly impossible to intercept or hack.
- Potential applications include sensitive communications in defense and finance.
- Current lab experiments achieve data transfer speeds of about 100 kilobytes per second.
- Future improvements could increase speeds to gigabytes or faster.
- The technology uses thermoradiative diodes to create hidden signals.
- Negative luminescence makes infrared glow appear darker, enhancing signal invisibility.
- The team is exploring less toxic materials and graphene for future developments.
