Printed electrodes for neuro-stimulation
CSEM SA
CSEM is a privately held, R&D center established in 1984 in Neuchâtel, Switzerland. From the beginning, CSEM has been committed to both applied and order-related R&D. This bridge function between economics and science is still a core aspect of the company, and CSEM has continuously adapted its research areas to the needs of industry.

CSEM is capable to fabricate all-printed electrocorticography arrays (MEA) by inkjet printing of platinum/gold electrodes and screen printing of polyimide as a passivation layer. The printed MEAs were based on ultra-pure platinum or gold ink formulations and are proven not to be toxic (bio-compatible). The printed platinum-based MEAs were used for in-vivo recording of a visually evoked cortical potentials in rabbits upon flash stimulation.
Electrode array size 1 to 32
Electrode line width 50-300 um
Electrode line length up to 10 cm
Electrode line thickness 0.1 to 1.0 (optional to several microns) um
Substrate material Polymide (Kapton)
Layout possibility custom design (kit with rules compatible)
Flexibility 100 000 cycles with bending radius 9.1 mm
Electrical resistivity < 500 (for a custom design) Ohm
Fabrication temperature (low-stress) close to room temperature °C
Bio-compatibility yes. Proved by in-vivo experiments on animal model
