Self‐Cooling Gallium‐Based Transformative Electronics with a Radiative Cooler for Reliable Stiffness Tuning in Outdoor Use (Adv. Sci. 24/2022)

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.
