It is to be noted that, this is the first attempt, and a comprehensive study on a packaged piezoelectric thin film impact sensor, and its application in non-destructive material discrimination. Piezoelectric sensors in particular are used … In this case it will be desirable for the sensing element to contact the bodies along the central region of each side of the sensing element, that is to say, so that the bodies contact the sensing elements on opposite sides of the central conductor, because along that region the direction of polarization will be parallel to the relative direction of motion of the bodies during the impact. This requires, on the one hand, precise processing of the crystal and component surfaces that come into contact with the crystal, and, on the other hand, the use of pre-stressed sensors. When the projectile is subjected to an impact, movement of the nose 3 and flange 5 toward the casing 3 will cause the surfaces 44 in the flange 5 to force the arms 4l of the holder 42 together, and thereby cause the piezoelectric coaxial cable l0 to be compressed symetrically about its axis by three surfaces. The grooves are of such a size that when the nose 3 and casing 2 are assembled, the coaxial cable l0 fits snugly within the grooves and is compressed by a force of not more than about l00 N per metre of cable. As, stainless steel is used for construction of piezo sensor switches, they can withstand the damage and are resistant to heavy use..
