An innovative system, which pairs an RFID-based passive sensor link with a ferrite-based power CET unit, is designed for a temperature-controlled heating system remotely located in a rotary machine tool. Capacitive and inductive coupling are integrated in a unique platform to implement the wireless data and power links, respectively. This ensures at the same time compactness and absence of cross coupling between data and power transfer. The rectifying part of a passive RFID tag is exploited to simultaneously power and read a Pt1000 temperature probe located in a inaccessible part of the rotary tool. The procedure to design layout-wise the system is described and an extensive experimental validation is discussed.

Abstract
An innovative system, which pairs an RFID-based passive sensor link with a ferrite-based power CET unit, is designed for a temperature-controlled heating system remotely located in a rotary machine tool. Capacitive and inductive coupling are integrated in a unique platform to implement the wireless data and power links, respectively. This ensures at the same time compactness and absence of cross coupling between data and power transfer. The rectifying part of a passive RFID tag is exploited to simultaneously power and read a Pt1000 temperature probe located in a inaccessible part of the rotary tool. The procedure to design layout-wise the system is described and an extensive experimental validation is discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
