Abstract

Novel kirigami-inspired microelectrodes, which utilize shape memory polymer (SMP) for spontaneous electrode shape control, were fabricated and tested in-vitro. The spring-shaped microelectrodes could be used in surface mounted implant devices to adaptively fit complex topography of the designated surface and to ensure good contact of each electrode. The gold electrodes were facilitated with SMP/Parylene C hybrid substrate and could fit gaps up to 4 mm. In the in-vitro test setup with 500 μm gaps, conventional planar electrodes lost the signals, whereas signal levels among the SMP kirigami electrodes were stable.
