Platinum-Iridium Wire — Biomedical Sensors & Neural Electrodes
Medical-grade platinum-iridium (Pt-Ir) alloy wire in 70/30 and 90/10 (Pt:Ir) compositions for biomedical electrode fabrication, neural recording probes, biopotential sensors, and high-temperature thermocouples. Pt-Ir combines platinum’s biocompatibility with iridium’s increased hardness and yield strength for durable, fine-wire electrodes.
