With the help of our collaborators, Eywa Neuro is proud to bring to you our own formulation of polyamic acids. Our synthesis and characterization capabilities allow us to supply you with low polarity, biocompatible polyimides which you can spin coat over a wide range of thicknesses.
Eywa Neuro combines state-of-the-art MEMS technology and our Ultra-Flexible polymer thin films to bring to you biocompatible, high-channel-count customizable neural microelectrodes. Our probes are currently available in India.
Our PCB Design engineers can design and layout sophisticated designs that can aid with your neural interface backend, or make custom micro-wire headstages for you. Be it adaptors, custom connectors or flex circuits, Eywa Neuro can help provide solutions to your engineering problems. We also manufacture flex and rigid printed circuit boards as well.
For ECoG, or EMG applications, Eywa Neuro offers its medical-grade Silicone-based electrodes. These electrodes come in custom designs with an option to have Stainless Steel, Platinum, or Silver/Silver Chloride as the electrode material.
Eywa Neuro's needle electrodes come in monopolar, bipolar, and concentric forms and are used for localized stimulation and population recordings. These electrodes are customizable for length, with a medical-grade Stainless Steel outer electrode and either a Platinum, Tungsten, Copper or Stainless Steel inner electrode. These electrodes are popularly used in Invasive EMG and Stimulation Studies.
Eywa Neuro can perform microfabrication research studies which include photolithography, deposition, etching, electroplating and device measurements. Please scroll below to see a detailed list of our microfabrication capabilities.
We provide contact lithography and direct-write lithography services for patterning micro and macro electrode features.
CD: Contact Lithography 3um +/- 0.2um
CD: Direct Write Lithography 5um +/- 0.5um
Eywa Neuro has the capability to do
1. Spin-coating (Polymers)
2. PECVD (Silicon Oxide, Silicon Nitride)
3. E-Beam And Thermal Evaporation (Au, Ti, Pt, Ag, Ni, TiO2)
4. Atomic Layer Deposition (SiO2, Al2O3, HfO2)
5. DC/RF Magnetron Sputtering (Au, Ti)
Our etching portfolio is extensive and ranges from wet etching to dry reactive plasma etching. We hold the capability to wet etch Al, Ti, Au, and Cr, and have CFx, Fluorine, and Chlorine Ion-based etching chemistries.
Eywa has extensive expertise in polymer etching recipes, and we can tailor-make O2 ICP-RIE recipes for your desired sidewall angle, etch rates, selectivity and isotropy.
Eywa understands your stimulation and recording needs, and hence we offer a variety of PEDOT-based ECPs and Au electroplating services.
