What is a digital twin?

A digital twin is a live virtual copy of a physical object or system, fed by real sensor data, that mirrors how the real thing is behaving right now. You can watch it, test changes on it, and predict problems before they hit the physical version.

Picture a virtual model of a production line that updates as the real line runs. You can ask what happens if you speed up a machine or reroute a process, and see the answer on the twin before you touch the floor.

That is the power: experiment safely on the copy, then act with confidence on the original.

Sthenos connects physical systems to software through Internet of Things and analytics, the foundation a digital twin runs on.

Is a digital twin just a 3D model?

No. A 3D model is static. A digital twin is fed by live data, so it reflects the real thing’s current state and can predict what comes next.
