A digital twin is the virtual equivalent of a physical system. It accurately tries to reflect whatever happens to the physical system in the virtual world so that we can do predictive maintenance as well as design refinements. Knowing what happens to our physical system in the real world is an excellent way of refining our design.

FatigPro is an excellent SHM sensor for the digital twin concept. Being self-contained, wireless, and weighing only 10 grams with battery + electronics, it can be deployed by thousands around the structure at critical points. Best of all, once you deploy them, you can forget about them for the next 10-40 years. (depending on battery shelf life) Whenever the particular part of the structure comes to the specific “fatigue age”, it pushes a message to the user. FatigPro is progressive; so as the structure ages it will be pushing more and more messages so that you know for sure that the data is real and reflects the true nature of the physical system.
FatigPro DIGITAL TWIN is ideal for:
Wind turbines: With climate change wind speeds increasing and taking heavy toll on wind turbine structures. With FatigPro-based digital twin, you can accurately monitor what is happening to your wind turbine. This is an ideal SHM sensor for wind turbines.
Locomotives, high-speed rail lines: Knowing the health status of equipment is important for safety. FatigPro can tell you the health status of many parts.
Bridges: Bridges age after repeated fatigue cycles. FatigPro offers a unique and economical way of monitoring the health state of bridges through digital twins. It is much easier and less costly than any other alternative. More reliable too.
Cranes: Cranes age and get fatigued. Don’t you want to know their health state before they break and distrupt your operations?
Offshore drilling platforms: Offshore rigs get enormous beating from constant waves. FatigPro can accurately reflect the health state of all structural members through digital twins of the offshore rigs.

Marine vessels: Marine vessels go through enormous stress while riding waves. No wonder they break in half in the middle of the sea. FatigPro offers an excellent and reliable way of the monitoring the health state of marine vessels through digital twins.
Aircraft structures: FatigPro can accurately monitor the structural health state of the aircraft. FatigPro solution costs less, weighs less, and requires fewer installation costs.
Power Pylons, tall lamps, Overhead road signs: These things are normally not much of a concern so far because monitoring their SHM was prohibitively expensive. With FatigPro now it is feasible to monitor the health state of much physical equipment through their digital twins.
