  • Publication number: 20200268307
    Abstract: A swallowing movement measuring device measures an examinee's swallowing movement. The device measures a movement of the examinee's larynx when the examinee swallows a food bolus. This device has a capacitive sensor to be brought into contact with a body skin of the examinee's laryngeal part, and a measuring unit that measures a change of the capacitive sensor in capacitance. This capacitive sensor includes a sensor body comprising sheet-like dielectric layer, a first electrode layer and a second electrode layer. The first and the second electrode layers are formed on a top surface and a bottom surface of the dielectric layer respectively, and are at least partially opposed to each other across the dielectric layer. The partially opposed portions of the electrode layers constitute a detection portion. The sensor body is reversibly deformable to change areas of the top and bottom surfaces of the dielectric layer.
