RESPIRATORY SENSING BELT USING PIEZO FILM

摘要

A respiratory belt sensing device to aid in monitoring breathing patterns of a user, particularly in diagnosis and treatment of persons with breathing disorders. The device includes a PVDF film member having first and second metalized major surfaces and a perimeter containing a plurality of spaced apart alignment features. It also includes a first tabbed lead and a second tabbed lead respectively attached to the first and second major surfaces of the PVDF film member by an electrically conductive adhesive. The resulting assembly is affixed to the surface of a body encircling belt member. Signals are generated when the PVDF film on the belt member is stressed due to stretching as a user breathes in and out. The generated signals can thereafter be used in diagnosis and analysis.
