Transformative Electronics

Gallium-based transformative electronics, which can convert between handheld and wearable forms, are vulnerable to a hot outdoor environment, which leads to unwanted softening of the electronics due to liquefaction of gallium. For the reliable rigid-mode operation in hot outdoors, the transformative electronics integrating a radiative cooler are developed to promote self-cooling through solar reflection and thermal radiation.
