Ultra-conformable tattoo electrodes for providing sensory feedback via transcutaneous electrical nerve stimulation.

ABSTRACT: Electrical stimulation of the peripheral nervous system has been demonstrated to be effective in restoring somatotopic sensory information in subjects with amputations. It can be achieved using invasive electrodes, which require surgical implantation, or non-invasive electrodes, which are applied directly to the skin. Whereas less selective, non-invasive electrodes offer the advantage of avoiding surgical procedures. Additionally, commercially available wet Ag/AgCl electrodes lack adaptability to the irregular surface of a subject's residual limb, leading to detachment during movement or use. This study aims to address some of the limitations of non-invasive electrodes by proposing and validating the use of ultra-conformable Parylene C-based tattoo electrodes to restore somatotopic sensory
