Summary

Story summary

The UNSW Sydney and Monash University research team, led by Professor Ned Ekins-Daukes and Dr. Michael Nielsen, developed a negative luminescence system using thermoradiative diodes to transmit hidden data.
The system makes signals blend into natural heat radiation and stay invisible to outside observers.
The system currently transmits data at 100 kilobytes per second and could reach gigabytes per second.
Future developments may use graphene to increase data transfer rates.
