Abstract

A sensor for detecting a property of a fluid sample, such as identifying the presence of an analyte in the fluid sample, comprises first and second resonant elements 1, 2 which are coupled together by a mechanical coupling such as a coupling beam 3. The elements 1, 2 are driven to oscillate by a drive means which may include drive electrodes 7. One of the resonant elements 2 is brought into contact with a sample of the fluid and the other resonant element 1 is kept substantially isolated from the fluid. Measuring the resonant behaviour of the elements in comparison to a baseline resonant behaviour can detect the property of the fluid. The sensor may be a microelectromechanical (MEMS) device. The resonant elements 1, 2 may be formed from silicon. The sensor can be used to determine the viscosity of a sample. A linear array (40, Fig 4) of such sensor devices is also disclosed.
