Abstract
A swallowing analyzing system (S) includes a swallowing sensor () and a swallowing analyzer (). A piezoelectric film sensor () of the swallowing sensor () includes a plurality of sensing portions (A) and (B) in a longitudinal direction of the neck region. The piezoelectric film sensor () is located within a range of movement of thyroid cartilage (), which occurs along with swallowing, and is attached to skin of an anterior neck region (). The piezoelectric film sensor () individually outputs analog signals (S) and (S) along with deformation of the plurality of sensing portions (A) and (B). A body () of the swallowing sensor () determines whether the swallowing occurs based on displacement signals that are low frequency components of the analog signals (S) and (S). The body () extracts data on the signals during the swallowing and wirelessly outputs the data to the swallowing analyzer ().
