Touch sensing passive RFID tag for man-machine interaction and use method

Abstract

The invention discloses a touch sensing passive RFID tag for man-machine interaction and a use method thereof. A microfluidic structure is used as a touch pressure sensing unit to adjust the working state of the RFID tag, so that the RFID tag returns to normal work when being pressed, and returns a tag electronic product code. The tag can also be used as a structural unit, and a plurality of unitscan be orderly arranged to form wireless man-machine interaction equipment. The tag is simple in structure, low in cost and convenient to process. The tag is completely passive and long in service life. The tag is ultra-thin, flexible, and foldable, and is easy to carry. The tag can be attached to various objects, even the surfaces of human bodies and clothes, and is convenient to use. The effective working distance is long and can reach up to more than ten meters without being limited by the sight distance. The same receiver can read input information of a plurality of devices at the same time.

Description

technical field [0001] The invention belongs to the field of antenna technology and wireless communication, and relates to a touch-sensitive passive RFID tag for human-computer interaction. Background technique [0002] Human-computer interaction technology (Human-Computer Interaction Techniques) refers to the technology of realizing the dialogue between human and computer in an effective way through computer input and output devices. In recent years, with the trend of miniaturization and portability of electronic equipment such as computers, requirements for miniaturization, light weight, and longer use time have been put forward for human-computer interaction equipment. Although new human-computer interaction technologies such as augmented reality (AR), virtual reality (VR), speech recognition, and gesture recognition are currently developing rapidly, they rely on image and speech recognition algorithms that are still in the development stage, and the accuracy still needs ...

AI Technical Summary

Problems solved by technology

[0004] 2. Use time: traditional wireless human-computer interaction devices are generally powered by batteries, and the use time is limited by the power;

[0005] 3. Adaptability: Traditional wireless human-computer interaction devices generally have a one-to-one correspondence between receivers and supporting equipment. When configuring multiple different wireless human-computer interaction devices on the same computer, multiple different receivers must be installed, which greatly occupies computer interface space
