| Outline of Final Research Achievements |
In this research, a novel measurement method for small mass is established. In the general sing, the mass is attached to the oscillator and from the shift of the natural frequency, the mass is estimated. Recently, much more accuracy sensing is proposed by coupled cantilevers. In this study, by using such coupled cantilevers, a novel excitation method for the cantilevers. Hence, we propose a method by which the coupled oscillators is self-excited under the velocity feedback. The resonance can be produced even in large viscosity environments for the measurement of biological samples.
