In neurophysiology, the cortical pyramidal neurons, activated with a certain degree of coordination, generate an electrical field that is detected by means of electrodes placed on the scalp. The monitoring of such signals allows for early detection of normal and abnormal physiological functions and to prevent disease development through an effective therapy. Non-invasive measurement of human’s biopotentials is one of the first approaches in assessment of a pathological health condition. These evaluations provide valuable input for the successful application of these ultrathin electronic tattoos sensors in multimodal brain monitoring and diagnosis.

Furthermore, a custom-made skin phantom platform demonstrates the feasibility of high-density recordings, which are essential in localizing neuropathological activities. 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. Here we present the performance of inkjet-printed conducting polymer tattoo electrodes in clinical electroencephalography and their compatibility with magnetoencephalography. Evaluations of brain activity in clinical practice face multiple limitations, where such electrodes can provide realistic technological solutions and increase diagnostics efficiency. These epidermal electronic devices offer a conformal and imperceptible contact with the wearer while enabling good quality recordings over time. They have successfully demonstrated their performances in the monitoring of various electrophysiological signals on the skin.
