Permanently safe flanged joints are the basic requirements for stable production processes and work at a high safety level. Recently developed silicon-based MEMS sensors are applied to bolt heads and measure their deformation due to changes in the preload force
At the CiS Research Institute, silicon-based MEMS sensors are being developed for testing safety-relevant bolted connections. Such special bolts can be used for example in mechanical engineering, materials handling and wind power plants
Dr. Thomas Frank, head of the MEMS department at the CiS Research Institute, explains miniaturized silicon strain sensors, 50 times more sensitive than a conventional metallic foil strain gauge and as small as the head of a pin, on April 4 at 15:00
