<p>PROBLEM TO BE SOLVED: To simplify mounting and equip with a heartbeat sensor that does not involve any feeling of incompatibility and the inconvenience of mounting by providing a signal processing means extracting a heartbeat waveform in accordance with electrical signals detected from electrodes provided in two places of the ear contact portions or the nose contact portion of a eyeglass type frame. SOLUTION: Electrodes 1 and 2 are attached to the ear contact portions of right and left earpieces 4 and 5 provided on an eyeglass type frame 6. And a voltage signal as an electrical signal detected from the electrodes 1 and 2, is sent to a signal processing means 10 from signal wires 7 and 8. At this time, the electrode 1 attached to the right or left earpiece 4, 5 of the eyeglass type frame 6 is made a reference electrode and the electrode 2 is made a signal electrode. When this eyeglass type frame 6 is worn, the electrodes 1 and 2 contact the right and left ears of a wearer and a potential difference between the right and left ears produced in association with the pulsation of blood of the wearer appears in the electrodes 1 and 2. By detecting this potential difference, the device can know a pulse of the heat, that is, a heartbeat.</p> |
