Abstract: A measurement device is provided for measuring a vessel pulse signal of a specific position attached by a mark. The measurement device includes a sensor, a plurality of conductive dots, a determination unit, and a measurement unit. The conductive dots are located around the sensor. The determination unit determines whether the plurality of conductive dots are connected to each other through the mark to generate a determination signal to indicate whether the sensor has been disposed in the specific position.

Abstract: A measurement device is provided. A sensor senses a vessel pulse waveform of a specific region of an object to generate a vessel pulse signal in a measurement mode. In the measurement mode, a first electrode generates a first potential signal, and the second electrode generates a second potential signal. A first analog front-end circuit digitizes the vessel pulse signal to generate a digital vessel pulse signal in the measurement mode. In the measurement mode, a second analog front-end circuit obtains an electrocardiogram signal according to the first and second potential signals and digitizes the electrocardiogram signal. A memory stores the digital vessel pulse signal and the electrocardiogram signal. A processor determines a polarity of the electrocardiogram signal in the measurement mode to indicate that the specific region is on a left or right part of a body of the object.
