NFC Capacitive Sensing IoT Use Case

June 2, 2022

According to Market Research Future, the global capacitive sensor market was valued at 27.03 billion in 2019 and the CAGR between 2020 and 2027 is predicted to be 5.2%.

Near field communication (NFC)-enabled capacitive sensing technology benefits the demanded
market by simply adding high-security to the solution.

Identiv’s Capacitive Fill Level Sensing Tag is the first passive NFC-enabled capacitive sensing
solution for fill measurement. Handled as a label, the tag is attached to an item, such as a liquid-filled container, and the level is sensed by capacitance. Users do not need an external sensor or special equipment for measurement.

NXP’s NTAG® 22x DNA StatusDetect, connected to a capacitive structure in a label, makes it
possible to read out capacity when interrogated with an NFC reader, such as a smartphone. It is
the first and currently only commercial passive NFC-enabled capacitive sensing solution for fill-
level measurement.

“Liquid waste and inaccurate measurements are chronic issues in the consumer, healthcare, and food and beverage industries. This leads to lost resources and profit for businesses and their customers. For industrial applications, it is difficult to measure fill level without opening the container, or to measure fill levels in containers that cannot be opened at all. The solution to help cut down on liquid waste and create a more seamless measuring process is an accurate sensor that is small and simple to use without any additional equipment.”
