Title:
MASS MEASURING DEVICE AND CANTILEVER
Document Type and Number:
WIPO Patent Application WO/2008/069247
Kind Code:
A1
Abstract:
It is possible to measure micro masses of a plurality of objects to be measured all
at once. It is necessary to prepare a multi- lever having a plurality of cantilevers in
which a piezoeresistance element is embedded. Different measurement object attracting
materials are painted on the multi-lever. The multi-lever is vibrated by a single
vibrator. The vibration frequency is sweeped within a predetermined range
so as to detect a resonance frequency of each of the cantilevers. The frequency change
is detected before and after throwing of the of the respective measurement objects
so as to calculate the mass changes.
