Inspired by the compound eyes of the fiddler crab in nature, we have developed a novel panoramic and amphibious imaging device by integrating a flat and graded-refractive-index micro-lens array with a comb-shape silicon photodiode array.

Based on radiative cooling, flexible/Non-metallic porous polymer removes thermal adverse effects of wearable optoelectronics under direct sunlight, while allowing wireless power transfer and data communication.

Inspired by the aquatic vision in nature, we have developed a novel miniaturized wide field-of-view imaging device by integrating a monocentric lens and a hemispherical silicon nanorod photodiode array.

M13 bacteriophage-based colorimetric sensors to facilitate the rapid detection for pathogens, toxins, or environmental changes at extremely low concentration levels

Covert polarization display to break through the flexibility/scalability limitation by using ultrathin lossy nanocolumns deposited on a metal film with wide color selectivity.
