Towards MEMS-based chem/bio sensing arrays with on-chip optical read-out

Abstract: Sensing on the microscale using microelectromechanical systems (MEMS) has established itself commercially as one of the dominant world-wide sensing technologies, providing commercialised sensing solutions for pressure, inertia, temperature, as well as for more challenging applications in remote infrared imaging and energy harvesting. However, to date MEMS has not delivered any commercially successful chem/bio sensor, even though it has been established for some time that microcantilever-based sensing can detec… Show more

“…The SNR of our sensors are enhanced by the low transduction noise level of optical vibrometry compared to that found in traditional electrical readout circuits. Moreover, recent advances have shown that on-chip optical detection 49 is becoming practical. Further, we have previously shown that careful construction of electrical transduction circuits can produce superior SNR compared to optical transduction 50 .…”
