Graphene and silk combine to make self-healable, multifunctional electronic tattoos

8 марта, 2019 - 08:11
Electronic tattoos (e-tattoos) are an extremely thin form of wearable electronics. They are lightweight and soft, which allows them to be intimately mounted on human skin for noninvasive, high-fidelity sensing. During the operation of e-tattoos, they are constantly exposed to external mechanical inputs such as bending, twisting, pressing, and cutting, which may cause mechanical damage and lead to malfunction. Now, researchers have demonstrated a self-healing silk e-tattoo that shows high sensitivity to multiple stimuli, including strain, humidity, and temperature based on a unique graphene, silk fibroin, Ca2+ combination.
