The developments in structural health monitoring techniques have led to the invention of
various sensors that can be effective damage indicator. Due to environmental or …

This review paper summarizes a new flexible sensor concept based on the microstrip patch
antenna technology. The principle of the patch antenna as a sensing element and the …

The conventional resonant-type microwave microfluidic sensors made of planar resonators
suffer from limited sensitivities. This is due to the existence of several distributed capacitors …

This paper presents a microwave sensor using a pair of split-ring resonators (SRRs). The
sensor is designed by loading a microstrip transmission line by two identical SRRs on its …

This research investigates a passive wireless antenna sensor designed for strain and crack
sensing. When the antenna experiences deformation, the antenna shape changes, causing …

All mechanical structures are subjected to deformation and cracks, due to fatigue, stress,
and/or environmental factors. It is, therefore, of uttermost importance to monitor the …

This paper presents the design, simulation, and validation experiments of a passive (battery-
free) wireless frequency doubling antenna sensor for strain and crack sensing. Since the …

Chipless Radio Frequency Identification (RFID) has been used in a variety of remote
sensing applications and is currently a hot research topic. To date, there have been a large …

Abstract Wireless sensors for Structural Health Monitoring (SHM) is an emerging new
technology that promises to overcome many disadvantages pertinent to conventional, wired …

This work presents the design, fabrication, and characterization of a printed radio frequency
identification tag in the ultra-high frequency band with multiple sensing capabilities. This …
