Microwire Arrays (MWA)

Implantierbare Mikroelektrodenträger, Platin/Iridium - MicroProbes


Designed for chronic experiments, the MicroProbes Microwire Arrays (MWA) provide the optimum in flexibility and affordable alternative for the neuroscience community.


  • Up to 32 penetrating wires per array for short- and long-term recordings.
  • Custom wire length (5-23 mm), including different length for each row.
  • Custom spacing between wires is in the range of 250 - 1000 µm.
  • Custom wire diameter options available (25/50 µm).
  • Custom impedance for individual wires between 200-800 kΩ.
  • Stainless steel and Platinum/Iridium fine wires with teflon or polyimide insulation material.
  • Custom reference and ground electrodes according to the researcher’s requirements.
  • Optionally integrated fiber optic and/or drug delivery cannula.
