Water Leakage inside Vehicles - a Thing of the Past Window seals, weather stripping and body seams are the primary causes of factory water leakage inside cars. Those leaks will soon become a thing of the past, as SMARTRAC launched the first-ever passive water sensor that works on metal surfaces like the harsh environment of an automobile chassis. The solution is successfully being tested in high-end OEM cars, ensuring that cars leaving the factory are completely watertight, and may also find further industry applications in aviation manufacture, shipbuilding or liquid packaging. SMARTRAC has teamed up with chip manufacturer RFMicron to develop a passive UHF sensor tag that is deployed inside cars during assembly. It can detect even small amounts of water leakage inside vehicle compartments
