Ultrasound Engineering

Ultrasound engineering is a discipline that encompasses a variety of industrial, medical, and scientific applications based on the use of high-frequency sound waves. Through technological innovation and ongoing research, ultrasound has evolved to become a fundamental tool in numerous industries. In this white paper, we will explore in depth the applications, scientific principles, advancements, and future potential of ultrasound engineering.
 

Scientific Foundations of Ultrasound

Ultrasound is a mechanical vibration with frequencies above the audible limit for humans (20 kHz). It is generated by piezoelectric transducers that convert electrical energy into sound waves. These waves can travel through different media (solids, liquids, and gases) and produce various physical and chemical effects, depending on their frequency and intensity.

Characteristics of Ultrasound:

• Frequency: Can vary from 20 kHz to several GHz, depending on the application.
• Wavelength: Determines the penetration and resolution capacity.
• Physical effects: Cavitation, molecular vibration, localized heating.
• Chemical effects: Generation of free radicals, acceleration of chemical reactions.
