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.

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.File in questo prodotto:
