A device employing 40kHz ultrasound waves to induce cavitation, the formation and implosion of microscopic bubbles in a liquid, is used in various applications. This process generates intense localized heat and pressure, impacting the target material. For example, it’s used in aesthetic treatments to target fat cells beneath the skin’s surface.
The specific frequency of 40kHz is chosen for its effectiveness in particular applications, offering a balance between penetration depth and energy intensity. This technology provides a non-invasive alternative to traditional methods like liposuction, offering potential advantages in safety, cost, and recovery time. Its history spans several decades, with advancements in transducer technology leading to its more widespread adoption in recent years. The controllable nature of the cavitation process enables precision targeting and minimizes damage to surrounding tissues.
