Description
Ke Xu and a large team of co-authors build a space-ready sensing chip in a 2026 paper. Watching the Sun and other celestial activity from orbit needs hardware that is fast, frugal, and tough under radiation. Wide-bandgap semiconductors suit harsh space conditions, but their plain transistors cannot compute. The team set out to give one such material a brain-like computing role.
Their device uses a phase of gallium oxide whose internal polarization can flip by atomic sliding. Built into a transistor, it senses deep ultraviolet light, stores states, and computes in one unit. The chip held up from deep cold to strong heat and under ion bombardment. A reservoir computing system built on it recognized celestial activity with up to 95 percent accuracy.
