Wi-Fi

Wi-Fi too is a kind of radio wave. It’s growing fastly to nearly replace Ethernet and create a wireless world. But, in the recent times, we’ve also seen a staggering rise in the number of media reports claiming that Wi-Fi is harmful to your health.

No issues, your Wi-Fi router may soon be able to tell how you feel, even if you have a good poker face.

A team of researchers at MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed a device that can measure human inner emotional states using wireless signals.

Dubbed EQ-Radio, the new device measures heartbeat, and breath to determine whether a person is happy, excited, sad, or angry.
