Ultra-flexible microelectrode array nanostructured by FIB: A possible route to lower the device impedance
Fabrication of ultra-flexible microelectrodes arrays (MEAs) is reported. The electrodes are nano-patterned by using focused ion beam technique. In vitro analysis is performed in KCl 100mM solution to simulate the brain environment. The impedance behaviour is investigated by changing the pitch of the pattern and the depth of the nano-holes.
