A programme of testing has been undertaken to determine the susceptibility of piezoelectric paint to environmental degradation and so to evaluate its suitability for use in shock and vibrations sensors on large outdoor structures. Controlled weathering trials show that the sensors drop in sensitivity over the first few months from manufacture, but thereafter maintain a constant sensitivity irrespective of exposure to sunlight or rain, frost, etc. Field trials on river crossing bridges in UK and Finland have shown that the sensors can survive harsh outdoor conditions and remain functional for six years, with no sign of an end to their lives at that time. © 2007 Institute of Materials, Minerals and Mining.
