Scientists produced the antennas, explained online September 21 in Science Advances, utilizing a water-based ink consisting of 1-nanometer-thick flakes of titanium carbide. The ink can be sprayed, painted or printed onto different products, such as paper, glass or material, or made into freestanding movies.
Products researcher and engineer Yury Gogotsi and coworkers at Drexel University in Philadelphia produced bendy radio antennas by overlaying titanium carbide movies onto sheets of polyester or filter paper. The movies varied from 62 nanometers to 8 micrometers thick– as much as about the width of a red cell. At about 6 centimeters long, these antennas send out and get radio signals at 2.4 ghz, a frequency typically utilized for Wi-Fi and Bluetooth interactions.
Gogotsi’s group likewise utilized titanium carbide movies to make radio frequency recognition tags, much like the antitheft tags connected to product at outlet store. The scientists’ superslim ID tags can be scanned as much as 8 meters away. “You can envision unmanned shops, where every product has a basic and inexpensive [identification] tag, and those tags are immediately checked out when a consumer leaves the shop” to charge that individual’s account, Gogotsi states.
