WISE Technology

Supersonic Technology

With our patented technology, we can produce stretchable conductive electrodes on substrates as thin and soft as desired

WISE’s Supersonic Technology enables the embedding of metal nanoparticles inside a custom-shaped polymer base, to form a conductive layer below its surface

Electrically neutral nanoparticles are shot at high velocity toward the polymer base. Thanks to their inertia, the nanoparticles are implanted inside the polymer as bullets fired at a soft target, forming a conductive nanocomposite layer.

With our technology, we can manufacture electrodes that are strongly attached to the polymer and are stretchable, flexible, biocompatible (medical grade) and allow effective stimulation and recording. Furthermore, our technology allows us to embed electrodes in foils as thin as a few microns, without damaging the foil itself. We can produce electrodes with any number of contacts of any shape, density or size, ranging from micro to macro scale.

The Supersonic Technology is protected by patents granted in Europe, USA, Israel, Canada, India, Japan and Korea.


Electrodes manufactured with our Supersonic Technology can sustain significant deformations, such as bending and stretching. They are highly robust – they do not deteriorate upon thousands of extensive repeated elongations

Our stretchable electronics can be shaped, bent or stretched, while remaining conductive and without losing functionality.


During the Supersonic implantation process, we are capable of micrometric patterning, thus producing a multitude of conductive wires, micro-electrodes or complex circuits

Micropatterning is possible by using rigid reusable masks that are not in contact with the substrate, avoiding the use of chemicals that could affect biocompatibility.


Contrary to standard manufacturing processes for flexible electronics, the Supersonic metallization process does not require any chemical treatment, heating, or electrical charging

This allows us to avoid polymer carbonization. Biocompatibility of WISE’s electrodes is further guaranteed by the use of metals that are standard for medical implants, such as platinum or iridium.

Effective stimulation

Our electrodes exhibit a very high surface area due to their nano-roughness

This means they are highly efficient both for stimulation and for recording, as shown by electrochemical testing. The low impedance at low stimulation frequencies and the very small polarization of WISE’s electrodes pave the way to better and more efficient stimulation and lower IPG battery consumption.
