Abstract

This paper presents a mass sensitive biosensor utilizing a Lame' mode micromachined resonator. The mass sensitivity of the sensor has been investigated. A biosensor with Q value of more than 10,000 and mass sensitivity of -400Hz/ng, has been demonstrated at a resonant frequency of 37.8MHz. Frequency shift in response to additional mass is simulated in COMSOL. The obtained results show that the Lame mode micromachined resonator has a potential to be used as an alternative to the QCM biosensors.
