Science Fiction Network, December 13 (Liu Yazhu) Recently, a paper published in the Nature sub-journal said that the integration of advanced magnetic metamaterials into daily clothing can allow wearers to achieve digital interaction with nearby NFC (near-field communication) devices.
Previously, the flashpoint of brush face payment was hot throughout the network, and the explosive point of payment and purchase without a mobile phone made everyone flock to it. This new invention can not only be used to pay, but also has the function of driving the door, brushing the access control, taking the subway, etc., these functions that can only be effective through keys, mobile phones or access control cards are all gathered on the clothes and solved in one thing.
In the future, if you want to open the door, you only need to wear a piece of clothing with an NFC function, you can send a signal or open the door within a range of 1.2 meters, knowing that the traditional NFC function can only take effect within 10cm. But the disadvantages of the clothes are also obvious, can only stay in cold water for 20 minutes, so it is necessary to develop more durable new materials to ensure that the sensor is not damaged in repeated washing.
It is reported that this wireless communication technology does not contain batteries itself, so it needs to rely on external power supply. And if the arms are crossed vertically, it can also realize "human-to-human" communication and realize data "connectivity".
