摘　　要：Temporary tattoo electrodes are the most recent development in the field of cutaneous sensors.They have successfully demonstrated their performances in the monitoring of various electrophysiological signals on the skin.These epidermal electronic devices offer a conformal and imperceptible contact with the wearer while enabling good quality recordings over time.Evaluations of brain activity in clinical practice face multiple limitations,where such electrodes can provide realistic technological solutions and increase diagnostics efficiency.Here we present the performance of inkjet-printed conducting polymer tattoo electrodes in clinical electroencephalography and their compatibility with magnetoencephalography.The working mechanism of these dry sensors is investigated through the modeling of the skin/electrode impedance for better understanding of the biosignals transduction at this interface.Furthermore,a custom-made skin phantom platform demonstrates the feasibility of high-density recordings,which are essential in localizing neuropathological activities.These evaluations provide valuable input for the successful application of these ultrathin electronic tattoos sensors in multimodal brain monitoring and diagnosis.
