When an object receives sunlight, and an image of the object reaches the retina of an eye with wavelengths of RGB colors, a red color, a green color, or a blue color of the RGB colors is recognized by 7 million cone cells of the retina, and a potential based on the number of photons of the RGB colors is created. When the potential reaches the retinal pigment epithelial cells in the occipital lobe that is responsible visual processing, the potential based on the number of photons of RGB colors is recognized, various intermediate colors are created according to intensity of light by the potential of the RGB colors, and an image having colors expressed on the entire area is created. According to the present invention, the visual signal is converted into an electrical signal by an electrode attached to the back of the retina of an eye where the image having colors expressed on the entire area is formed, or the occipital lobe that is responsible visual processing, and the electrical signal undergoes amplification, modulation, and demodulation processes so that the electrical signal corresponding to each electrical signal of an electrical device is transmitted to an LED of a TV monitor. Accordingly, the entire image is displayed when each LED of a TV monitor is turned on according to a potential difference of the electrical signal or intensity of the current. The same process is applied to hearing. An electrode is applied to the temporal lobe, an auditory signal generated from the electrode undergoes amplification, modulation, and demodulation processes, and the converted auditory signal is reacted with a coil and a magnet of a speaker while a vibration plate connected to the core moves up and down. Therefore, a sound is generated. According to the present invention, a biometric visual or auditory signal can be outputted through a TV monitor or a speaker.COPYRIGHT KIPO 2020물체가 태양빛을 받아서 RGB등의 주파수로 눈의 망막에 도달하게 되면 망막의 700만 원추세포에서 RGB 적추체 또는 녹추체 또는 청추체가 인지하여 각 각의 RGB 색깔의 광자수에
