Incredible, but true is an Origami microscope that you build folding the paper.
This just demonstrate that using LEDs it can provide over 2,000X magnification with sub-micron resolution (800nm), weighs less than two nickels (8.8 g), is small enough to fit in a pocket (70 × 20 × 2 mm3), requires no external power, and can survive being dropped from a 3-story building or stepped on by a person.
Its minimalistic, scalable design is inherently application-specific instead of general-purpose gearing towards applications in global health, field based citizen science and K12-science education.
Based on true science, its just demonstrate that low cost microscopes as the ones we mention previosly are possible combining structured light with hypersampling.
