A New System for Acoustoelectronic Gas Sensors Analysis

Acta Physica Polonica A, 2013
Typical approach to the surface acoustic waves sensors response analysis is based on the use of self-oscillating circuits with surface acoustic wave device working inside positive feedback loop of an ampli er. Such kind of parametric measurement allows to track the center frequency of the sensor changes in particular.

ELECTROMECHANICAL PROGRAMMER FOR ACOUSTOELECTRONIC SENSORS OF PHYSICAL QUANTITIES

Sensor Electronics and Microsystem Technologies
An electromechanical programmer is described, intended for programming an acoustoelectronic angular displacement meter, constructed on the basis of the effect of dependence of the phase velocity of surface acoustic waves on the direction of propagation relative to the crystallographic axis of a piezoelectric sound conductor.
