Oscillator for Biosensors based on Quartz Crystal Microbalance (QCM)
Revista Facultad de Ingeniería Universidad de Antioquia, 2012 Quartz crystal is generally used in some applications as a microbalance taking advantage of its capacity to change the resonance frequency according to any surface mass change on the resonator. In this way a quartz crystal can be used as a transducer in
