ABSTRACT:
A portable apparatus having an accelerometer device and a supporting element in the accelerometer device, having a first body of semiconductor material integrating a sensor element that detects movements of the first body and generates a signal correlated to the detected movement; a second body of semiconductor material that integrates a conditioning electronics and that is electrically connected to the first body; and conductive bumps that provide electrical connection of the first and second bodies to the supporting element. In particular, the conductive bumps connect the first and second bodies to the supporting element without the interposition of any packaging.
