Abstract
A device for measuring psychological signals includes a substrate, a light emitting unit, a photoelectric sensor and a microprocessor. The substrate includes a surface that is divided into an emission area and a reception area. The light emitting unit is arranged in the emission area and includes a plurality of light emitting sections. The plurality of light emitting sections irradiates a plurality of lights with different wavelengths on a predetermined location. The photoelectric sensor is arranged in the reception area, and is capable of detecting a plurality of reflected lights from the predetermined location and generating an electrical signal accordingly. The microprocessor is electrically connected to the photoelectric sensor, receives the electrical signal, and converts the electrical signal into a waveform signal. Thus, the detection accuracy can be improved. As such, the detection accuracy of the psychological condition of the user can be improved.
