Abstract: Conductive polymer hydrogels have emerged as a promising new class of materials to functionalize electrode surfaces for enhanced neural interfaces and drug delivery. Common weaknesses of such systems are delamination from the connection surface, and the lack of suitable patterning methods for confining the gel to the selected electrode site. Various studies have reported on conductive polymer hydrogels addressing one of these challenges. In this study we present a new composite material which offers, for the f… Show more

“…Release studies were performed using microfabricated probes each comprising a single iridium oxide (IRO x ) electrode (diameter of 2.0 mm, surface area of 0.03 cm 2 ) and a platinum (Pt) contact site based on a Pyrex substrate as illustrated in Figure a. The detailed fabrication process was described previously by us . In brief, the metallization was sputter coated and patterned onto the Pyrex substrate using standard photolithographic techniques.…”

“…For this study, a relatively large electrode area was chosen to facilitate the quantification of the released substances. Nevertheless, it should be noted that the hydrogel can be photolithographically defined to coat electrodes as small as 20 µm without any problem …”

“…One challenge is the fabrication of hydrogels and their coupling with electrical contacts in devices. To this end, microfabrication of photo‐crosslinkable hydrogels using conventional photolithography techniques can afford the spatial resolution required for device fabrication . Bao et al achieved 18 µm arrays of PANi hydrogel using chemical cross‐linking.…”

“…Bettinger and co‐workers used aqueous‐phase transfer printing to fabricate PEG‐based hydrogels on Pt microelectrode arrays with enhanced interfacial adhesion between hydrogels and the Pt metal . Covalent chemical bonding between the hydrogel and the electrodes also improves hydrogel adhesion and reduces delamination . Another challenge is the long‐term stability and batch‐to‐batch reproducibility that will need to match the ones of metal and carbon electrodes for translation to clinical settings.…”
