Design, optimization and characterization of LC sensors for wireless measurement of moisture concentration in building materials

Abstract

Pasivni bežični LC senzori projektovani su u tehnologiji štampanih kola (PCB) i u tehnologiji nisko-temperaturno pečene keramike (LTCC). Predstavljena su tri tipa LC senzora izrađenih na PCB-u u jednoslojnoj i dvoslojnoj štampi. Takođe su prikazana i dva tipa LC senzora izrađenih u LTCC tehnologiji. Karakterizacija senzora je izvršena u laboratorijskim uslovima a za testiranje korišćeni su građevinska opeka i siporeks blok kao jedni od najčešće korišćenih materijala u građevinskoj industriji za zidane objekte.Passive LC wireless sensors are designed in technology printed circuit boards (PCB) and the technology of Low Temperature Co-Fired Ceramics (LTCC). Presented are three types of LC sensors made on the PCB in the monolayer and bilayer press. It also presents two types of LC sensors manufactured in LTCC technology. Characterization of the sensor is carried out in the laboratory for testing were used building bricks and aerated concrete block as one of the most commonly used materials in the construction industry
