Flexible, Graphene-Based NFC Antenna for Secure Data Transfer

Along with being the thinnest, strongest, and lightest known material, graphene is flexible, impermeable, and electrically and thermally conductive. Researchers from Italy's National Research Council have developed a graphene-based near-field communication (NFC) antenna, and unlike today's NFC antennas the new devices are more flexible and durable. NFC technology can transmit small amounts of data wireless only within a close range while other methods, such as Bluetooth and Wi-Fi, have a wide transmit range. NFC technology is used to identify objects because with such a close transmitting range, it is more secure and less vulnerable to data hijacking. NFC technology is used for sharing files from mobile devices and NFC devices are used in contactless payment systems. The researchers have now designed an antenna that could exchange information with near-field communication devices such as a mobile phone, matching the performance of conventional metallic antennas. The graphene-based NFC antennas are chemically inert, highly resistant to thousands of bending cycles, and can be deposited on different standard polymeric substrates or silk tissues.

00:00:23 and NFC Tag antennas are based and take advantage High conductivity like our credit C is based on antenna NFC antenna typically Made Of Metal what we have done is to create the same antenna based on graine based material this can be processed easily on different kinds of substrate and Plastic and completely compatible with actual electronic So this is a commercial we

00:00:55 REM the metal Anten and our based Anten and this We can see that it works can be read with normal mobile PH when you put it here it makes be and reads what that has detected a graph flagship antenna Any Kind Of application that can be done with the metal containing antenna can be done with this kind of [Musik] material
