Novel chemical sensors have been developed based on piezoelectric quartz resonators coated with chemically engineered copolymer resins. These have been employed for the selective detection in aqueous solution of K over other Group I ions such as Li and Na . A quartz crystal microbalance, QCM, opera

An oscillator circuit is proposed that simultaneously excites and tracks two harmonic resonances in a piezoelectric resonant sensor that, in particular, can be a quartz crystal resonator (QCR) sensor. By probing the resonator at two harmonic modes at the same time, enhanced sensing capabilities can
