Abstract
The electrical response of chemical bulk acoustic wave sensors depends on changes in the surface mass loading and changes in the viscoelasti c properties of the coating material. We consider here the acoustic be haviour and the electrical response of a quartz-crystal resonator to c hanges in surface mass and shear parameters of the coating material. B oth a glassy and a rubbery polymer have been investigated. The frequen cy changes of an oscillator are calculated from a full transmission-li ne model, an impedance approximation and Sauerbrey's or Martin's equat ion. (C) 1998 Elsevier Science S.A.
