Abstract:
This study introduces a novel approach for strain measurement by employing antenna sensors and Radio Frequency IDentification (RFID) readers. The functionality of passive antenna sensors is based on the alteration of resonant frequency due to structural deformation. Custom software was developed to manage RFID readers and collect data on the relationship between signal strength and frequency. The system was validated through experiments tensile strain of aluminum plates with antenna sensors and strain gauges. The antenna sensors showed an error of 5% compared to strain gauge measurements, which confirms the feasibility of using antenna sensors. Antenna sensor technology is anticipated to be utilized in various fields in the near future.
