Abstract Scope With the increasing intricacy of neural electrodes, there is also an increase in the need for highly strain-resistant fabrication materials. Additionally, these electrodes must remain highly conductive to allow for maximal action potential resolution in vivo. One promising neural electrode material is an exceptionally conductive vertically aligned carbon nanotube (VACNT) supercapacitative sheet. In this study, we fabricate VACNT supercapacitors grown directly on thin aluminum foils using only conductive support layers in a scalable, low-pressure chemical vapor deposition (LPCVD) process. Specific capacitances for five growth times (5, 10, 15, 20 and 25 minutes) were measured to be 30 to 79 F g-1 with power densities for all supercapacitor sheets exceeding 3 MW kg-1. Our study demonstrates the benefits and applicability of fabricating VACNTs on metal substrates using scalable techniques for flexible and conductive supercapacitors which may evolve into excellent neural electrodes with high strain resistance and electrical conductivity.
