Polymer Cuff Electrodes Prove Viable for Selective Peripheral Nerve Stimulation
A team at Imperial College London has validated fully polymeric conductive elastomer nerve cuffs as effective alternatives to metallic electrodes for fascicular-selective peripheral nerve stimulation. Published in the Journal of Neural Engineering in 2026, the study combined ex vivo experiments on rat sciatic nerves with microCT-informed computational modelling, achieving selectivity indices above 0.65 across all three target fascicles. Advent Research Materials supplied the precision PTFE-insulated silver wire used as electrical interconnects within the electrode assembly.
Tungsten Microelectrodes Help Map How Early Alzheimer’s Pathology Spreads Through the Brain
A 2026 study in The Journal of Physiology from the University of Castilla-La Mancha and Pablo de Olavide University tracks how early amyloid-β accumulation disrupts brain circuit activity across connected regions. Using Advent 50 μm tungsten microelectrodes implanted in the posterior parietal cortex, researchers revealed a precise temporal sequence: hippocampal dysfunction emerges within hours, spatial memory deficits by day one, and measurable cortical oscillatory disruption by day three.
