The method includes cutting a metal layer to form a plurality of electrode sites, contact pads and metal traces connecting the electrode sites to the contact pads. A first silicone layer including a mesh is formed and coupled to the metal layer. A second silicone layer is formed and laminated to the first silicone layer coupled with the metal layer. Holes are formed in the first or second silicone layer exposing the contact pads and electrode sites.

Patent number: 10264988Abstract: Systems and methods are disclosed herein for recording electrical signals in the presence of artifacts. The system and methods can employ multiple techniques for attenuating large, unwanted artifacts while preserving lower amplitude desirable signals. Aspects that can improve the recording of electrical signals in the presence of larger artifacts include particular electrode placement and spacing, high dynamic range amplification with good linearity, and signal blanking. Combinations of more or fewer techniques can be employed to achieve the desired attenuation of signal artifacts while preserving the desired signal. The systems and methods are suitable for recording neural signals in the presence of electrical stimulation signals.Type: GrantFiled: May 20, 2016Date of Patent: April 23, 2019Assignee: THE CHARLES STARK DRAPER LABORATORY, INC.Inventors: Brian Nugent, Robert Bousquet, Jesse J.
