Abstract
Systems and methods for achieving levitation via a photophoretic effect are provided. In certain embodiments, a structure of ultralight materials is provided, for example a BoPET film and carbon nanotubes and has a top and bottom side, made of two separate materials. When the bottom side is illuminated by light at certain intensity, it can result in an upward lift force being applied to the entire structure, causing the structure to levitate.
