Tech Needs of the Week

Technology is required to enable real-time detection of defects during the welding process. This could be achieved by a system that monitors parameters during the welding process and then analyzes changes, ascertains the presence and location of a weld defect, and if possible, its nature. Potential solutions should be suitable for industrial production lines and could be added on to new welding equipment such as welding robots and industrial welding stations. The detection of a defect should take about 10 seconds. Click here for more info.

Techs of the Week

A cantilevered microbeam temperature sensor is free from the residual or induced stress characteristic of standard bridge-type strain gauges. The microbeam is supported at one end, and the other is free to oscillate relative to the substrate and is isolated from changes in strain caused from flexure of a diaphragm. The beam's natural resonant frequency varies in response totemperature changes. This occurs due to changes in the density and modulus of elasticity of the polysilicon microbeam in the same manner as the resonant beam of a typical strain gauge. The sensor can be placed adjacent to a strain gauge to ensure accurate temperature compensation. Click here for more info.
