  • Graphene Electronic Tattoos,” posted on February 20, 2023, by Dr. Dmitry Kireev. “Graphene Electronic Tattoos (GETs) are a type of skin-wearable electronic device that can be used for personalized healthcare by transmitting the bio-electrical activity of the human body in measurable electrical signal. […] The GETs are optically transparent, lightweight, and flexible, making them adhere and conform to the micro-curvature of the skin, which helps them to remain at the exact positions during use and transmit bioelectrical signals during movements (which would not be possible with other, thick and rigid materials such as gold or silver/silver chloride (Ag/AgCl) gel electrodes). GETs have been used to monitor electrophysiological signals such as the brain (EEG), heart (ECG), muscle (EMG), and ocular (EOG) activities, as well as skin temperature and hydration level.”
