FatigPro: A revolutionary new technology to follow SHM using an in-situ sensor

FatigPro is a practical sensor that follows the SHM at critical points of structural members. It can do this for years even without a battery. It does not need a connection to a computer and it works as a stand-alone device.

FatigPro:

  • Can work for years and follow SHM without needing any electrical connection,
  • The battery is used only for communication purposes and a small coin-size battery can last 40 years, (practically shelf life of the battery- if the shelf life of the battery allows.)
  • Sensor and electronics can be separated up to 5 meters, (or more if necessary). This means sensors can be located in a harsh environment while sensor electronics are located in a safer location.
  • The sensor can send a message to the user automatically when the SHM level exceeds the predefined level, (Unlike others our sensor “pushes” the data. This is edge computing at its best!)
  • Up to 7 fatigue levels can be defined which enable progressive monitoring of SHM levels,
  • Proven working in laboratory and field studies,
  • Works with real data; there is no simulation, no estimation
  • Excellent tool for predictive maintenance,
  • Excellent sensor for digital twin of real industrial equipment.

What is SHM- metal fatigue and what is our unique patented solution?

SHM- Metal fatigue is a serious problem. Please have a look at these to see the problem.

“It has been estimated that fatigue contributes to approximately 90% of all mechanical service failures”

F. C Campbell ASM International
Fatigue is a problem that can affect any part or
component that moves. Automobiles on roads,
aircraft wings and fuselages, ships at sea, nuclear reactors, jet engines, and land-based turbines are all subject to fatigue failures.

Bridge collapse and broken engine blades are attributed to fatigue….
This eight-bogie train derail is attributed to metal fatigue, SHM failure/

Ships break in half in the middle of the sea due to metal fatigue. Watch this terrifying video of a ship breaking in half in Karadeniz near Turkiye.

I hope you are convinced that this is a serious problem. But what causes it?

Please watch the video below which uses a very clever trick called motion amplification. It cleverly amplifies tiny motions on the structure so that we can see it.

As you see the structure and parts actually move even if we can’t see it with our naked eye. These tiny motions add up and cause fatigue failure. Now please proceed to the next page to see what makes fatigue such an insidious problem.
