Abstract

Microstrip patch antenna sensors have been demonstrated for strain, temperature, crack, moisture sensing etc. These antenna sensors are attractive because of their simple configuration, low profile, and conformability. Most of these studies, however, were carried out in lab settings using a specialized microwave instrument, which is expensive and has a low interrogation speed. This paper presents the development of a low cost interrogation system that can dynamically interrogate the antenna sensor and wirelessly transmit the acquired data to a smart device. The hardware implementation of the interrogation system as well as it characterization using a test apparatus imitate a prosthetic socket are presented. We demonstrated that the interrogation system can extract the resonant frequencies of the antenna sensors at real time.
