Abstract
A paint-applied digital imaging system may include a plurality of small pixel devices each including a photodiode, a battery, and an antenna. The plurality of pixel devices may be suspended in a liquid dispersion medium, such as a transparent paint, and brushed or rolled onto an extended surface, such as a wall. Each photodiode collects light, charging its battery, which powers the antenna. The antenna transmits a signal indicating the intensity of light incident on the photodiode to a base station. The signals sent by the plurality of pixel devices are received by the base station and converted into a digital image.
