Programmable Micro-Mirrors for Real-Time Emissivity Control and Switching (Case No. 2025-254)
Summary: UCLA researchers in the Department of Mechanical and Aerospace Engineering have developed a fast-switching, MEMS-based thermal metasurface that enables real-time infrared emissivity modulation via high-contrast, broadband radiative control. Background: Dynamic emissive thermal devices offer active control over infrared (IR) radiation....

A Small Aerial Drone for Covert Surveillance that Can Change Appearance
Conceals Wings or Blades to Camouflage Itself Within Urban EnvironmentsThis palm-sized aerial vehicle alters its shape to avoid detection. The small flyer, equipped with a camera and microphone, transforms into an inconspicuous object, such as a soda can, upon landing. In recent decades, unmanned micro-aerial vehicles (MAVs) have gained acceptance for...
