Spray-On Antennas?

Researchers at Drexel University’s College of Engineering have now tested a chemical formulation that could transform wireless communications between devices.

According to an article published on the Drexel website, researchers at the College’s Department of Material Science and Engineering have determined that MXene titanium carbide dissolved in water results in a conductive material that can transmit and direct radio waves. Even when sprayed or painted on a surface at thicknesses of tens of nanometers, the material is sufficiently conductive to transmit signals. By increasing the thickness to just 8 microns, the MXene antenna achieved a transmission rate equivalent to 98 percent of its predicted maximum value.

The researchers believe that the ability to embed or spray on a thin MXene-based antenna would greatly facilitate the deployment of antennas to transmit information between the next generation of Internet of Things (IoT) devices, since the material would add no weight to the device and not require a certain level of rigidity to function.
