APPARATUS AND METHOD FOR PULSE WAVE MEASURING

摘要

PURPOSE: A device and a method for measuring a pulse wave are provided to detect the optimum pulse wave in the unconstrained state by combining a plurality of light emitting devices and light receiving devices. CONSTITUTION: A pulse wave measuring device is worn in the wrist of a subject and includes a sensor(110) and a controller(120). The sensor detects the pulse wave signal of the subject and includes a plurality of light emitting devices(113,117) and light receiving devices(111,115). The controller is indirectly or directly connected to the sensor and processes the pulse wave signal detected by the sensor. The controller includes a switching unit. The switching unit controls the on/off of the light emitting devices and the light receiving devices.
