Drone-aided Localization in LoRa IoT Networks

Dario Floreano, Alexandru Rusu, Fabrizio Schiano, Giuseppe Cocco

Besides being part of the Internet of Things (IoT), drones can play a relevant role in it as enablers. The 3D mobility of UAVs can be exploited to improve node localization in IoT networks for, e.g., search and rescue or goods localization and tracking. On ...

Influence of atrial substrate on local capture induced by rapid pacing of atrial fibrillation

Jean-Marc Vesin, Vincent Jacquemet, Alexandru Rusu

Preliminary studies showed that the septum area was the only location allowing local capture of both the atria during rapid pacing of atrial fibrillation (AF) from a single site. The present model-based study investigated the influence of atrial substrate ...

Experimental confirmation of temperature dependent negative capacitance in ferroelectric field effect transistor

Mihai Adrian Ionescu, Giovanni Antonio Salvatore, Alexandru Rusu

In this paper, we report the basic design conditions and the experimental confirmation of a temperature dependent negative capacitance (NC) effect in a ferroelectric field-effect-transistor (Fe-FET). We find that the internal voltage amplification peaks of ...

Phase-locked loop based on nanoelectromechanical resonant-body field effect transistor

Mihai Adrian Ionescu, Alexandru Rusu, Sebastian Thimotee Bartsch

We demonstrate the room-temperature operation of a silicon nanoelectromechanical resonant-body field effect transistor (RB-FET) embedded into phase-locked loop (PLL). The very-high frequency resonator uses on-chip electrostatic actuation and transistor-bas ...
