Abstract
A snore sensor incorporating a piezoelectric polyvinylidene fluoride (PVDF) film material adapted to be adhered to the skin of a sleeping patient on the patient's throat for detecting mechanical vibrations due to snoring. The PVDF film has a layer of metallization on opposed major surfaces thereof which are insulated from one another by the PVDF material itself and elongated electrical leads individually connect to the metallization layers. One major surface of the film layer is covered by a layer of adhesive tape and the opposite major surface with its metallization is underlayed by a thin layer of plastic film having an adhesive on opposed surfaces thereof. The adhesive on one side of the plastic film layer adheres it to the PVDF film while the adhesive on the opposed major surface of the plastic film is used to adhere the device to the patient's skin.
