摘要：
The invention relates to a sensing apparatus for sensing an object. The sensing apparatus comprises an ultrasound unit (11) for ultrasonically sensing the object (4), an electrical energy application unit (9) for applying electrical energy to the object (4), and an ultrasound unit shielding element (16) for electrically shielding the ultrasound unit (11), wherein the ultrasound unit shielding element (16) is electrically connected to the electrical energy application unit (9). Since the ultrasound unit shielding element electrically shields the ultrasound unit, the ultrasound sensing of the object is less influenced by a capacitive coupling of the application of electrical energy, in particular, of an RF signal which may be used for applying the electrical energy, into the ultrasound sensing. A further reduction of this influence is achieved by electrically connecting the ultrasound unit shielding element to the electrical energy application unit.
