Learning from swarms: mini sensors for measuring the layer thickness of batteries

Summary:

Optical sensors especially for coating thickness applications are still upcoming for more and more scenarios as they tend to be fast and long lasting without “touching” the surface under inspection. Non-contact and non-destructive layer thickness sensors based on the photothermal principle are becoming increasingly important for measuring layer thicknesses in battery cell production. The sensors are able to measure the exact thickness of the cell coating within
