Definition
Electrochemical cell in which the working electrode is located on one surface of a piezoelectric quartz crystal, the oscillation frequency of which is measured.

Notes
1) The electrode may be chemically modified.
2) The change in resonant frequency (proportional to mass changes) is measured during electrochemical processes, such as linear scan voltammetry or cyclic voltammetry, giving simultaneous information on changes in mass and charge transfer.
