Characterization of ECG tattoo sensor. a Skin-electrode interface impedance measured for 13-μm-thick e-tattoo with Tegaderm tape (cyan) and skin adhesive (blue), 1.5-μm-thick e-tattoo with (magenta) and without (red) skin adhesive, and gel electrodes (black). b Upper panel: ECG signals synchronously captured by 13-μm-thick e-tattoo (blue), 1.5-μm-thick e-tattoo (red), and gel electrodes (black). Lower panel: zoomed-in ECG signal with characteristic peaks labeled. c Respiration rate captured by 13-μm-thick e-tattoo (blue), 1.5-μm-thick e-tattoo (red), and gel electrodes (black)
