Paper Abstract

It is needed to enhance sensitivity and resolving power in microresonators, which give weak frequency variation in perceiving pressure and temperature. The simulated extraction of weak frequency variation is carried out with the manifesting resonant frequency-locking property when system transits from chaotic to great periodic motion. With signal preprocessing used bandpass sampling and down sampling, measurement system is founded based on chaos. At the same time it is pointed out that the system can realize flexible measurement in silicon microresonators.
