摘要：
An apparatus and method can be configured to detect respiratory air temperature information and respiratory air pressure information from a patient using a first piezoelectric film and a second piezoelectric film, wherein at least a portion of the second piezoelectric film overlaps at least a portion of the first piezoelectric film. In an example, the first and second piezoelectric films can be sized and shaped to be disposed on an upper lip of a subject. In certain examples, the first piezoelectric film can include a non-overlap portion exposed to nasal respiration, and the second piezoelectric film can include a non-overlap portion exposed to oral respiration.
