Asygn Presents Revolutionary UHF Sensor Tag at #WIOTtomorrow20 DIGITAL

For the first time, reading ranges of up to 6 meters are possible – The Gen2 protocol ensures standardized application!

French semiconductor developer Asygn will present the brand new IC AS3213 at the RFID & Wireless IoT tomorrow 2020 DIGITAL.

Nicolas Delorme, CTO at Asygn, reports: "The AS3213 is the first UHF RFID chip that can measure bending strengths of materials completely passively, without any additional components and can transmit the acquired data to conventional UHF RFID readers over ranges of up to six meters".

No Special Hardware or Software Required

The data transfer from the chip to the reader takes only a few milliseconds and is completely compliant with the current EPC Gen2 protocol. Advantage for the user: No special hardware or software is required to acquire and process measured values. Readers currently available on the market are able to capture and interpret the data from the chip and forward it to higher-level systems.

When integrating tags based on the AS3213 chip into a logistics application, for example, the asset ID and EPC number can be captured together with the sensor data. There are two addresses in the memory for sensor data – one for strain data, and the other for temperature data.

A Wide Range of Applications, From Industry to Bicycle Rental

The first sensor ICs are already being used in real applications where traditional sensor solutions based on strain gauges were previously required – or where there was simply no suitable solution previously. Typically, a standard strain gauge requires signal conditioning circuitry, analog-to-digital converters, and communication devices to be able to transfer or provide the data to a PC.

With the AS3213, all the necessary components are combined in one chip. The strain gauge and signal conditioning circuitry is integrated into the chip itself and communication is possible via RFID. Neither batteries nor external sensors are required.

"Together with industrial customers, AS3213 chips have already been incorporated into elastomers in order to measure the loads from the inside. Another customer uses the chips in the transmissions of power generation plants. In another pilot project, the chips are applied to particularly stressed components at a bicycle rental company," explains Lionel Geynet, RFID & RF Project Manager at Asygn. 

High-Tech on a Tiny Surface Area 

The AS3213 UHF RFID chip has capacitive and resistive sensor interfaces, built on a very small silicon area of 1.45 millimeters by 1.66 millimeters. The passive UHF RFID chip has internal sensors to measure strain, temperature, ambient light, and contact. With a sensitivity of -13dBm, the chip is ideal for monitoring systems from a distance, according to the IC developers.

This sensitivity enables a reading range of up to six meters. Compared to a standard sensor tag with a maximum reading range of up to a meter, the AS3213 is truly revolutionary and enables a much wider range of applications and possibilities.

Inlays, based on the AS3213, are convertible into numerous transponder formats, from flexible labels to hard tags. A QFN package version with integrated sensor IC is suitable for use even in harsh environments. Compared to other metal-based strain measurement sensors, the AS3213 chip has a much higher gauge factor, ranging between 150-180.
