Abstract
A detonator for the electrical ignition or detonation of detonating materials, such as explosives. The detonator incorporates at least one piezo element which is at least partially encompassed by a secondary explosive. The piezo element is subjected to a steeply rising voltage impulse and thereby rapidly expanded so as to generate a shock wave which will detonate the secondary explosive.
