Abstract:
An acoustic delay line sensor for the detection of potassium
ion concentration in water has been implemented and
tested. The device uses the propagation of shear horizontal
(SH) waves in a piezoelectric plate (Love waves) in order
to minimize acoustic energy loss in the liquid. One of the
plate surfaces is covered with a Polyvinil chloride (PVC)
- valinomycin membrane, which is a well known ligand for
the detection of potassium ions. Measurements are here
reported in order to evaluate the performances of the device.
