くなるという欠点がある。PRIOR TECHNOLOGY Conventionally, this type of pulse sensor device detects the potential difference caused by heartbeat, or a certain amount of light from a light emitting body is incident on a photo sensor via an earlobe or a fingertip, and this incident light is detected depending on the size of the blood pulse. There was one that adopted a method that made the most of flow. However, in such conventional examples628,
In the former case, it is extremely difficult to obtain an accurate pulse pulse because the potential difference varies greatly depending on the subject and the patient's health condition.On the other hand, in the latter case, these light emitters and photosensors are attached to the earlobe or the other hand. It has the disadvantage that it must be worn on the fingertip, and that it consumes a large amount of magnetic force because the light emitter is always turned on.
