Innovation

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.

WISE can therefore produce stretchable electronics that can be arbitrarily shaped, bent or stretched, while remaining conductive and without losing functionality.

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.

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).

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.
