What is a Digital Twin?
A Digital Twin is a virtual representation of a real-world object, system, or process. Think of it as a “mirror” in the digital world that behaves exactly like its physical counterpart.
For example:
-
In manufacturing, a machine on the factory floor has a digital twin that collects live sensor data. If the real machine overheats, the twin also reflects that state. Engineers can test fixes on the twin before applying them to the real machine.
-
In healthcare, a patient might have a digital twin (built from health data) that helps doctors simulate treatments before giving them in real life.
The key idea is that the digital model is connected in real time to its physical entity using IoT (Internet of Things), sensors, and AI. This makes monitoring, prediction, and decision-making far more efficient.
