Abstract
A crack or rupture-detecting system comprising an electrically-insulating substrate which carries lines of electrically-conducting material formed of small electrically conductive particles which are in electrical contact. The substrate layer may be elastomeric when applied to the object to be protected, but later will crack or rupture if a crack or rupture occurs in the object and layer and thereby separate the particles in the conducting line or lines adjacent the crack or rupture.
