An apparatus for detecting physiological signals of the human body. The apparatus comprises a plurality of piezoelectric ceramic pieces (10), a signal collecting processor (20) and a power source (30). The piezoelectric ceramic pieces (10) are connected in series and/or in parallel through wires and are connected to the signal collecting processor (20), and the signal collecting processor (20) is connected to the power source (30). The piezoelectric ceramic pieces (10) can be dispersedly laid on a liner. In the apparatus, the piezoelectric ceramic pieces (10) are connected in series and/or in parallel through the wires and are connected to the signal collecting processor (20), and in the use process, the piezoelectric ceramic pieces (10) are laid below a mattress. The thickness of the ceramic pieces is small, and the thickness of the apparatus for detecting the physiological signals of the human body is equal to that of the ceramic pieces, so the apparatus is comfortable to use. The piezoelectric ceramic pieces (10) can be folded and collected together, and are thus convenient to store and carry. The piezoelectric ceramic pieces (10) are passive sensing devices, so energy is saved, and the piezoelectric ceramic pieces (10) can directly generate electrical signals when pressed and have sensitive response and better sensing effect.La présente invention concerne un appareil de détection des signaux physiologiques du corps humain.
