ABSTRACT

A laser technology for manufacturing implantable electrode arrays, using spin-on polydimethylsiloxane (PDMS) and platinum foil as materials, was investigated in respect to its scaling limitations. The following aspects were analyzed: Minimal width and centre-to-centre distance of platinum tracks, the ability of spin-on PDMS to flow between platinum tracks with very narrow gaps and the electrical insulation properties of thin spin-coated PDMS.
