Piezoelectric Paint in Finland

SpecialChem / Mar 17, 2008

Pressure-sensitive paint will warn when a bridge is about to collapse. VTT Technical Research Centre in Helsinki, Finland, added piezoelectric crystals, which produce a voltage when stressed, to a resin which was painted on the underside of a steel footbridge. Electrodes at each end of the bridge detected changes in voltage as people crossed the bridge. The crystals can be used to detect pressure changes due to structural flaws.
