Piezo-shockwave technology ESWT

Focused and precise

Piezo-ceramic elements are geometrically arranged on a concave surface so that when they are excited simultaneously by a brief, high-voltage pulse, they expand by a few micrometers to generate a pressure pulse. The piezo elements are precisely aligned so that each pressure pulse generated focuses in a specific area. This precise focusing of the pulse creates a shockwave at the point of focus.

The piezo shockwave’s „direct focusing” technology eliminates the need for additional refl ectors resulting in a compact therapy source design and a precise and well defi ned focal zone. The virtually painless therapy is applied quietly and energy levels can be freely adjusted with almost no adverse effect on the size of the focal zone. The piezo shockwave technology is extremely durable.

Piezo shockwave therapy sources are available with single-layer or double-layer technology, depending on the required energy levels.


The piezo shockwave technology uses interchangeable gel pads which contact the patient to ensure that the shockwave penetrates precisely to the desired depth with as little scattering as possible. These gel pads are used as spacers and change the penetration depth in increments of 5 mm. They accomplish this by drawing the therapy source’s static focal area incrementally superfi cial or deep respectively. Maximum penetration depths of between 4 and 5 cm are possible, depending on the therapy source.
