TRANSDUCTION UNIT OF NON-CONTACT HUMAN BODY SLEEP PHYSIOLOGICAL PARAMETER DETECTION SENSOR

摘要

A transduction unit of a non-contact human body sleep physiological parameter detection sensor, which transduction unit belongs to the technical field of piezoelectric films. The transduction unit comprises a circuit board (1), a piezoelectric film (2) and conductive adhesives, wherein the piezoelectric film (2) comprises a film sheet (21) and two electrodes, which are respectively arranged on two side faces of the film sheet; the piezoelectric film (2) is attached to the circuit board (1); and the two electrodes of the piezoelectric film (2) are respectively electrically connected to two exposed pad electrodes on the circuit board (1) by means of the conductive adhesives. The solution has a simple structure, is easily assembled and produced on a large scale, and also has high electromechanical conversion efficiency.
