Cameras are already embedded in a lot of devices, but what you could wrap them around things like a "skin?" That’s the premise of "flexible sheet cameras" developed by scientists at Columbia University. Rather than having just a single sensor, the devices use an array of lenses that change properties when the material is bent. The research could lead to credit card-sized, large-format cameras that you zoom by bending, or turn objects like cars or lamp posts into 360-degree VR cameras.
In order to create a wraparound camera, the team first considered attaching tiny lenses to single pixel-sized sensors, a tact that’s been tried before on curved surfaces. However, they realized that when bent, such an array would have gaps between sensors that would produce artifacts in the final image. Instead, they created flexible silicon sheets with embedded lenses that distort and change their focal lengths when bent. The resulting prototype has no blank spots, even with significant curvature, so it can capture images with no aliasing.
