The Use of Piezoelectric Materials for the Purpose of Creating Infrasound and Ultrasound Sources for Terrorist Acts

Abstract

The technological development of the last decades and the so-called revolution in military affairs have not only produced beneficial consequences for human society, but have also opened the possibility of developing new technologies for the benefit of the terrorist organizations. These include infrasound and ultrasound technology, sources with continuous or pulsed operation, capable of acting in a very discreet regime, being very hard to detect, also capable of causing serious harm to human health and even the death. The fact that such devices have the ability to act completely silently amplifies their dangerousness. The present paper aims to present a series of relatively simple technologies for making such weapons which can work with acoustic waves in the non-audible regime. The field is interesting and the rapid technological evolution leaves this chapter open to further debates.
