Abstract
A biological feature detection apparatus and an electronic device are provided. The apparatus includes a light emitting unit and a light receiving unit. The light emitting unit is configured to emit light to a detection surface of a biological tissue, the light emitted by the light emitting unit is processed by the biological tissue and then transmitted to the light receiving unit, and the light receiving unit is configured to receive the light and perform a photoelectric conversion to generate an original electrical signal for biological feature detection; the light emitting unit and the light receiving unit are attached to the detection surface of the biological tissue. As such, the signal-to-noise ratio of the original electrical signal is improved and accuracy of biological feature detection is enhanced.
