PWST and High Function RFID

The embedded slides were presented by Powercast at the Sensors Expo in Chicago on June 6, 2012. The presentation covers how RF power harvesting enables passive wireless sensor tags (PWST) and high-function RFID. What is high-function RFID? There’s no official definition, but view it as a class of devices that uses RFID for communications but also includes numerous other components for advanced functionality. The additional components may require significantly more power than is available from a regular RFID chip, and a battery may not be desired. RF power harvesting from and RFID reader can provide the extra power needed for these devices.
