Computers, mobile phones, automobiles, televisions, refrigerators, washing machines, etc., more and more electronic devices have the ability to be networked and intelligently operated. Now, even glass and paper can be networked!
Ericsson demonstrated glass networking at MWC in 2013, and at CES and MWC in 2014, Ericsson demonstrated paper networking, which can identify unique identity based on printed electronics and connect the human body as a line to connected smartphones. .
In the live demonstration of the paper networking, the visitors touched the beverage cup with one hand and touched the “human body†sensing device connected to the tablet with one hand. The beverage composition, calorie value, beverage transportation mode and transportation distance were visually visible.
According to reports, paper networking can make it easier for us to get information about all kinds of things. Any print can be identified as a user by touch. After identifying it, I can process it and get the corresponding information. For example, is a cup of drink good for health? Is it good for health? How is this drink produced? How is the quality? How to transport? How long is it transported? This content can be obtained through the interconnection of information in the paper.
In addition to information about beverage packaging and access to food safety and nutrition, paper networking can also be used to package any item to display content related to objects within the package.
Regarding the principle of paper networking, it is not difficult to understand that the printing contains identification information, such as media information. Touch it, you can get the identification information, and convert it into a variety of video, text and other forms, displayed on the phone and other terminals.
In the future, paper will also be part of the connected world, and it will be digital, not just an ordinary piece of paper, and the paper itself will be part of the network.
It is understood that behind the "paper networking", there are two key technologies: First, Printed Electronics refers to the manufacture of electronic devices by printing on the surface of various objects, and the so-called printing method. , refers to printing in the traditional sense, including lithography, inkjet printing and screen printing. At the end of the last century, scientists in the United States and Japan discovered that polymer materials doped with iodine to conduct electricity, and in 2000 won the Nobel Prize, opening the door to printing electronics.
Printed electronics is suitable for applications that are widely distributed, low cost, and low performance requirements. At present, things that can be printed include antennas, sensors, batteries, solar modules, simple displays, diodes, storage, and a small number of transistors. Although the current transmission capabilities are not comparable to traditional communication methods, they have been able to carry hundreds of bits of transmission, as well as some simple sensor processing.
The second is Connected Me ("I am the network" human interconnect technology), the concept of human body communication, capable of demonstrating capacitive coupling technology and touch transmission at speeds up to 10Mbps. The human body is equivalent to a circuit with both resistance and capacitance. Through capacitive coupling, we can use the human body as a network cable to transmit data to or receive data from mobile devices.
From the Internet to the mobile Internet, from the Internet of Vehicles to the Internet of Paper, we have reason to believe that any ordinary device that is like your own paper, like a smartphone, can be connected to the Internet and can be intelligently controlled. The function. What is certain is that although the concepts of the Internet of Things, the network society, and the mobile 2.0 are different, they all point to a vision, that is, the Internet of Everything, and this vision is not far away from us.
