In this work we discuss the design of a near-field link, based on capacitive plates, operating in the 868 MHz band, usually adopted for far-field applications. This system, capacitively coupled, serves as a wireless information transfer unit in a temperature-controlled system. Capacitive and inductive coupling are simultaneously exploited to integrate in a unique, robust, and reliable platform the...
Wireless power transfer (WPT) is foreseen as a key enabling technology for energy-autonomous wireless sensors, Internet of Things and Device to Device communication. RF energy, either scavenged from the ambient or intentionally provided to a wireless device, can be successfully exploited for autonomously sustaining its operations. In this paper we overview the main aspects to be addressed for a successful...
In this paper we introduce for the first time the concept of exploiting the rectifier part of passive RFID systems not only for sensor powering but also for remotely performing the sensor reading. This solution is proposed for harsh industrial environments where remote machineries parts need be simultaneously powered and monitored wirelessly. We demonstrate the co-existence of high wireless power...
