ABSTRACT

Techniques have been developed for the manufacture of PZT filled polymer thick-films and their use as dynamic strain sensors. This material takes the form of a water based paint which can be applied using standard paint spray techniques onto clean but otherwise unprepared surfaces and which cures at ambient temperature.

These sensors have been shown to give a linear response over two decades of strain amplitude (40 – 4000 μstrain) and three decades of frequency (1.0Hz – 1.2kHz). This paper describes field trials to be undertaken on the Gateshead Millennium Bridge over the River Tyne during summer 2001 and results will be presented in a poster at the conference.
