1. A transduction unit of a non-contact human sleep physiological parameter detection sensor, comprising a circuit board, a piezoelectric film and conductive adhesives, characterized in that the piezoelectric film comprises a film sheet and two electrodes, which are respectively arranged on two side faces of the film sheet; the piezoelectric film is attached to the circuit board; and the two electrodes of the piezoelectric film are respectively electrically connected to two exposed pad electrodes on the circuit board via the conductive adhesives;
one of the electrodes of the piezoelectric film that faces towards the circuit board is connected to one of the exposed pad electrodes on the circuit board via one of the conductive adhesives; one of the side faces of the film sheet that faces towards the circuit board is further provided with a transfer electrode; and another of the conductive adhesives is connected, at its one end, to the transfer electrode and another of the exposed pad electrodes on the circuit board, and is folded, at its opposite end, to another of the side faces of the film sheet through an edge of the film sheet, so as to be connected to the electrode on the another side face.
