Cost‐Effective Ti/Al/Ni Multilayer Neural Probes With In Vivo Recording Performance Comparable to Ti/Au Neural Probes

open access: yesAdvanced Electronic Materials, EarlyView.
In this study, we developed a cost‐efficient neural probe by replacing traditional gold with an aluminum‐based Ti/Al/Ni multilayer stack. Optimizing this metal architecture suppressed oxidation and ensured robust electrical stability, achieving signal quality comparable to standard gold probes. It enables a highly accessible and economical solution for
