FIRST LOOK: Itera, a newly unveiled deep tech startup, is betting it can remove one of hardware engineering's biggest bottlenecks: how long it takes to change a circuit. The company has developed what it calls a "fluid circuit board," a system that allows engineers to reconfigure physical circuit paths on demand rather than fabricating a new board for every design change.
In an email to Tom's Hardware, Itera described the underlying approach as a form of electrowetting, where electric fields are used to precisely move liquid metal alloys across a glass substrate. Instead of relying on fixed copper traces, the system dynamically forms connections by shifting conductive liquid, effectively redrawing the circuit in place.
That capability goes after a familiar pain point in electronics development. Traditional PCB iteration is slow and expensive, requiring fabrication, assembly, and testing cycles that can stretch across days or weeks. Itera's system aims to compress that loop dramatically by allowing engineers to modify a design and see it implemented on real hardware almost immediately.
"Software developers have been able to write code, test, and iterate in real time for decades. Itera makes real-time design and iteration possible for hardware too," said AJ Cooper, CEO and co-founder of Itera. "Hardware has always been hard because it is permanent. Changing it requires time and money. Itera is making hardware easy. For the first time ever, an engineer can change a circuit and test it again before their coffee gets cold."
