Shielding is crucial for all manner of electronic devices. Whether you want to keep power supply noise out of an audio amplifier, or protect ICBMs against an electromagnetic pulse from …read more Continue reading MXenes Make Faraday Cages You Can Turn On And Off
With the explosion in cell phones, WiFi, Bluetooth, and other radio technologies, the demand for antennas is increasing. Everything is getting smaller and even wearable, so traditional antennas are less practical than ever. You’ve probably seen PCB antennas on things like ESP8266s, but Drexel University researchers are now studying using titanium carbide — known as MXene — to build thin, light, and even transparent antennas that outperform copper antennas. Bucking the trend for 3D printing, these antennas are sprayed like ink or paint onto a surface.
A traditional antenna that uses metal carries most of the current at the skin …read more
