The accidental swallowing caused by decline of the ability to swallow due to aging is a severe problem for elder people. Therefore, effective methods of monitoring swallowing action and estimating swallowing function are required. In this paper, a piezoelectric film sensor is developed to estimate the swallowing function. To investigate the relationship between swallowing action and sensor output behavior, pharynx movement is measured by using the piezoelectric film sensor and three-dimensional motion analysis system. In experiments, we measured the swallowing action during repetitive saliva swallowing test that is a major screening test for dysphagia by using the developed sensor system. As a result, it is found that number of swallowing can be evaluated by using the standard deviation of the developed sensor output.
