ABSTRACT:
A miniaturized sensor device comprises at least one pair of active projecting elements or cantilevers, which are set parallel to one another and at a micrometric or sub-micrometric distance apart and are designed to be submerged at least partially in a fluid. Each pair comprises a first cantilever, equipped with actuator means, and a second cantilever, equipped with sensor means. The actuator means can cause a movement of the first cantilever, whilst the sensor means can detect a movement of the second cantilever, induced by the movement of the first cantilever, for generating accordingly a measurable signal, which represents the lubricating capacity of the fluid.
