| Abstract Scope |
The Cleveland Open-Source Modular Implant Innovators Community (COSMIIC) aims to create an open-source, modular platform for neuromodulation therapies. COSMIIC’s system relies on conducting electrical stimulation from a pulse generator to an implanted nerve excitation module, as well as relaying information back to biopotential recording modules. This work discusses mechanical testing for the connections in COSMIIC’s Neural Open-Source Versatile Array (NOVA), which consists of a non-commercially available 32-channel lead intended to serve as an intermediary for sensing and stimulation.
To represent NOVA’s lead-to-feedthrough-pin interface, witness specimens were fabricated using a platinum alloy pin encased in an epoxy cylinder. A stainless-steel ferrule containing a 1x7 arrangement of 35N LT silver-cored, drawn-filled tube insulated strand was welded to the pin. Specimens were tested in tension and fracture surfaces were evaluated using optical light microscopy and scanning electron microscopy. Data will be used to improve the lead-pin interface and inform future design. |
