Linear Microelectrode Array v2

LMAv2

Introduction

The 2nd-generation Linear Microelectrode Array (LMAv2) features a number of key improvements over the original LMA, including a new tapered shaft profile and an improved tip shape. This allows for a thinner, sharper probe that retains the many customizability advantages of the LMA.

User Specify

  • Long-tapered shank keeps the shaft thin (< 200 µm where the contacts are located, while widening a distance from the tip to provide for more contacts and a more rigid probe.
  • Sharper, less abrupt tip shape than the original LMA improves tissue penetration.
  • Hard, durable tungsten tip that can itself be set as a recording contact, or ground or reference.
  • Each shank may contain 4 to 32 contact sites.
  • Contact sites may be positioned anywhere on the shaft surface (minimum spacing 75 µm), allowing for endless possibilities (helices, rings, clusters, opposing columns, etc) .
  • Contact sizes 15, 25 µm.
  • Multiple contact sizes allowed in each shaft, allowing researchers to mix and match functionality at different depths.
  • Platinum/iridium contacts.
  • Platinum Group EPIC coating is available, reducing impedance by an order of magnitude for the same sized contact.
  • 3D arrays of multiple shanks are available.
  • Fixed or flexible-cable configurations available.
