It’s obvious that in the future we will have enormous number of IoT sensors and since they’ll mostly communicate wireless – they’ll all need a proper antenna. It’s quite challenging for engineers to construct proper antenna for such a small sensor that can be placed on all the unusual places. Another challenge that will have a great impact on the antenna construction is the “appearance design” – people like to see “cool and sexy” gadgets and they are especially not keen to see antennas as they warns people about the RF radiation. It seems that some researchers have a solution for the challenge – Drexel’s MXene Antenna Spray Paint. The concept basics is to just spray titanium carbide material “MXen” on any object to become an antenna. For details about research of Drexel University’s team read the full article here.
