PURPOSE:To stably detect cardiograph, by using the capacitor electrode as the cardiograph detection electrode, through avoiding the direct contact of electrode and skin and reducing the effect of contact resistance and polarization potential. CONSTITUTION:The insulator 31 formed with SiO, SiO2 or Si3O4 in gas phase growing method avoids the inductive electrode 32 placed on the wrist watch case 33 from being directly contacted with the skin. On the surface of the metal case 34 of the wrist watch constituting opposing electrode of the inductive electrode 32, glass thin film 35 is welded to avoid the metal case 34 from being directly contacted with the skin. The cardiopotential between right and left hands induced between the inductive electrode 32 and the metal case 34 is amplified 36, and the period is measured by taking the signal frequency dividing the time standard signal of the watch or this signal as the clock pulse, and digital display is made by converting it into the number of pulsations per one minute. |
