Abstract

The invention discloses an MEMS-sensing integrated ultrahigh frequency RFID label, comprising an MEMS sensor substrate and an ultrahigh frequency RFID substrate integrating into one body. The MEMS sensor substrate comprises a mechanical component, a component for transferring the mechanical quantity into the electricity quantity, and a signal processing circuit. The mechanical component, the component for transferring the mechanical quantity into the electricity quantity and the signal processing circuit are connected sequentially. The ultrahigh frequency RFID substrate comprises a micro-printed antenna, a radio frequency circuit module, an analog circuit module and a digital circuit module. The micro-printed antenna, the radio frequency circuit module, the analog circuit module and the digital circuit module are connected sequentially. The invention further discloses a read-out device for the label. The RFID label chip of the invention can acquire 10-microwatt energy at ten meters away through the micro-printed antenna. The integration of the MEMS and the RFID single chip can solve the difficult problems with the instant power connection, instant read-out and instant power off of a traditional chip. The label and the read-out device can transmit the real-time information of a sensor.

Description

technical field [0001] The invention relates to the field of RFID, in particular to an ultra-high frequency RFID tag integrated with MEMS sensing and a readout device. Background technique [0002] Today's trends, whether it is the development of the Internet of Things, the upsurge of smart phones, or the rise of mobile networks, are closely related to sensors. Sensors have penetrated into our daily life and exist in every corner, ranging from automobiles, industrial equipment, to mobile phones, all of which use a large number of sensors-this is in line with the trend of intelligence, and sensors are the most basic It is also the most important part. [0003] There are various types of sensors, so they are classified according to their usage and principle. Such as proximity sensors, Hall sensors, temperature / pressure sensors, current sensors, etc. Sensing technology has also made great progress in recent years. MEMS is the most representative example. A complete MEMS is c...
