Abstract
The utilization of quartz-crystal-microbalance sensors in liquids yields ne w requirements to the applied interface circuits. In the present article, t he fundamentals of the measuring principle and advantages and drawbacks of suitable interface circuits are discussed. Special requirements of oscillat ors as interface circuits are outlined. Possible solutions to those require ments are investigated and two recently developed oscillator circuits are p resented.
