Paper Title
A Self-Sustained Battery-Less MEMS based Sensor Node through Far Field Wireless Powering

Abstract
This paper details on the sensor nodes (SNs) for aircraft surface sensing, especially operating them on the far - field wireless powering, also known as RF powering. The SNs includes RF energy harvesting circuit, harvesting voltage booster, data link transceiver and sensor interface circuits. Modelling & Simulation of the most critical block in the link, RFDC converter is described. The RF-DC converter exhibits more than 25% efficiency even with the input power levels less than -18dBm. Thus, without exceeding the FCC emission limits, the base station is able to wirelessly power the SNs up to 10 m range.
