Abstract
Purpose
This paper aims to present an context evaluation and frequency measurement method for surface acoustic wave (SAW) resonant sensor.
Design/methodology/approach
This method is based on a signal subspace construction, which, along with assembling optional value set, provides the results.
Findings
The method can assess the application context and improve the resolution and accuracy of the passive wireless SAW resonator sensor system.
Originality/value
Passive wireless SAW resonators have been used as sensor elements for different physical parameters such as temperature, pressure and force in a number of industrial and medical applications. Various wireless channel environments introduce different application contexts.
