WISE s Supersonic Technology consists in embedding metal nanoparticles inside a preformed polymer base in order to form a conductive layer below its surface.
The electrically neutral nanoparticles are produced in the form of a supersonic beam and are shot at a 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.
WISE s technology allows to produce electrodes that are strongly attached to the polymer and are stretchable, flexible, biocompatible (medical grade) and allow a very effective stimulation. Furthermore, it allows to embed electronic circuits in foils as thin as a few microns without damaging the foil itself. WISE s technology has been protected by granted patents in Europe, USA, Israel, Canada, India, Japan and Korea.

Stretchability
The Supersonic Technology allows to produce conductive systems
that can sustain very large deformations, such as bending and stretching, and that do not
deteriorate upon thousands of extensive repeated elongations.
WISE can therefore produce stretchable electronics that can be arbitrarily shaped, bent or stretched, while remaining conductive and without losing functionality.
Micropatterning
During the Supersonic implantation process, it is possible to pattern with micrometric resolution, producing a multitude of conductive wires, micro electrodes or complex circuits.
The micro-patterning can be obtained using rigid reusable masks that are not in contact with the substrate, avoiding the use of chemicals that could affect biocompatibility.

Biocompatibility
Contrary to standard manufacturing processes for flexible electronics, the Supersonic
metallization process does not require any chemical treatment.
In addition, the process does not require heating or electrical charging, thus avoiding polymer carbonization. Finally, the biocompatibility of WISE selectrodes is further guaranteed by the use of standard metals for medical implants (Pt, Ir).

Effective stimulation
Thanks to the high roughness of their surface, the electrodes produced with our technology exhibit a very high surface area.
As a consequence, WISE s electrodes have a very high efficiency 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.
