E-Tattoos: Toward Functional but Imperceptible Interfacing with Human Skin

Chemical Reviews, Journal Year: 2024, Volume and Issue: 124(6), P. 3220 - 3283

Published: March 11, 2024

The human body continuously emits physiological and psychological information from head to toe. Wearable electronics capable of noninvasively accurately digitizing this without compromising user comfort or mobility have the potential revolutionize telemedicine, mobile health, both human–machine human–metaverse interactions. However, state-of-the-art wearable face limitations regarding wearability functionality due mechanical incompatibility between conventional rigid, planar soft, curvy skin surfaces. E-Tattoos, a unique type electronics, are defined by their ultrathin skin-soft characteristics, which enable noninvasive comfortable lamination on surfaces causing obstruction even perception. This review article offers an exhaustive exploration e-tattoos, accounting for materials, structures, manufacturing processes, properties, functionalities, applications, remaining challenges. We begin summarizing properties effects signal transmission across e-tattoo-skin interface.

Background: The effects of electroencephalography (EEG) and functional magnetic resonance imaging (fMRI)-neurofeedback on brain activation behaviors have been studied extensively in the past. More recently, researchers begun to investigate near-infrared spectroscopy-based neurofeedback (fNIRS-neurofeedback). FNIRS is a neuroimaging technique based hemodynamics, which easy use, portable, inexpensive, has reduced sensitivity movement artifacts. Method: We provide first systematic review database fNIRS-neurofeedback studies, synthesizing findings from 22 peer-reviewed studies (including total N = 441 participants; 337 healthy, 104 patients). (1) give comprehensive overview how training protocols were implemented, (2) online signal-processing methods used, (3) evaluate quality using pre-set methodological reporting criteria also present statistical sensitivity/power analyses, (4) effectiveness modulating activation, (5) its changing behavior healthy pathological populations. Results discussion: (1-2) Published are heterogeneous (e.g., targets, investigated populations, applied protocols, methods). Large randomized controlled trials still lacking.
