Physiological Signal Measurement Apparatus Capable of Automatically Adjusting a Measure Position and Method of Utilizing the Apparatus

摘要

A physiological signal measurement apparatus is capable of automatically adjusting a measure position and suitable for installed on a support element to measure a physiological signal of a user. The physiological signal measurement apparatus includes a movable element, a physiological signal sensing element, a pressure sensing unit and a microcontroller unit. The movable element has a first pressure. The user exerts a second pressure on the physiological signal sensing element, and exerts a third pressure on the support element. The pressure sensing unit senses the first pressure, the second pressure and the third pressure to generate a first pressure signal, a second pressure signal and a third pressure signal. The microcontroller unit receives the physiological signals and the pressure signals, and controls the movable element by the pressure signals and the physiological signals, in order to increase the quality of signal measurement.
