Practical Implementations of Passive and Semi-passive NFC Enabled Sensors

Abstract

In this publication several near field communication (NFC) based sensor demonstrations and related measurements are discussed. These include basic temperature sensor applications and some more complex scenarios with external sensors and actuators. The reader device can be a commercial NFC enabled mobile phone or specially developed hardware. Based on the experience gathered with demonstrations and prototypes, the main features of an optimal NFC circuitry for low cost battery less NFC enabled sensor devices are specified.
