Figure 5: Biosignal monitoring using skin-like electrode.
From: Solderable and electroplatable flexible electronic circuit on a porous stretchable elastomer
(a) Skin electronics mounted on a finger. (b) Despite excessive finger bending, the LED shone brightly without experiencing a decrease in the light intensity (white dotted circle indicates an electric power connection). ECG signals recorded using (c) a Au-Ti-deposited plaster ECG electrode and (d) a commercial Ag/AgCl electrode. X-axis scale bar indicates 1.0 s (red: resting, green: walking and blue: after exercise). (e) The skin after 1 week of continuously wearing the Au-Ti-deposited plaster ECG electrode; no skin irritation was observed. (f) Hematoxylin and eosin (H&E) stained tissue after 8 weeks implantation of the electrode on the back of a mouse. Scale bars indicate 1 cm (e) and 100 μm (f).
