Abstract: The technology of this application relates to an image sensor and an electronic device, to increase photosensibility, improve utilization of light that is incident to the image sensor, and reduce crosstalk between bands. The image sensor includes at least one photosensitive pixel. Each photosensitive pixel includes a plurality of nano antenna layers. The plurality of nano antenna layers are arranged in an overlapping manner. Each nano antenna layer includes at least one nano antenna. The at least one nano antenna is configured to generate resonance for incident light. Different nano antenna layers generate resonance for incident light of different bands or different polarization directions. An output signal of the nano antenna layers is used to obtain an image.
