Some tattoos truly make the heart go pitter-patter.
In rats, a graphene “tattoo” stuck to the heart could treat an abnormally sluggish beat. Like a futuristic pacemaker, the device delivered electrical signals that kept the heart pumping properly, scientists report online March 25 in Advanced Materials.
The electronic device is currently a proof of concept, but a version for use in human hearts could be ready for testing within five years, estimates Igor Efimov, a cardiovascular engineer at Northwestern University in Chicago.
Efimov and his colleagues have worked for years creating implantable devices that conform to the body. A main challenge is how to marry rigid electronics with soft, sometimes throbbing tissues. For most current pacemakers, doctors thread electrodes on long wires through a vein inside the heart. Every time the heart beats, some 100,000 times per day, the wires flex. Enough flexing, and the device eventually breaks, Efimov says. One solution is to use ultrathin materials that ride along with the heart’s movements, like plastic wrap clinging to quivering Jell-O.
In 2021, Efimov saw something that looked promising: a paper on graphene devices applied to the skin like temporary tattoos. Unlike the metal components often used in electronics, graphene is “atomically thin,” says Dmitry Kireev, a biomedical engineer at the University of Texas at Austin who developed the graphene tattoos.

Isn’t that the crap that’s been found in the covid shots?
Igor Efimov...................You can’t make this stuff up!.................
Not all graphene is bad news. Did you read the original article?
Let me know the results when they actually do it on humans. I don’t give two shits about what happens in RATS.
They should try absinthe.
Henry Fonda: Why absinthe?
Absinthe makes the heart grow, Fonda!
Let me guess, fully jabbed and boosted too?
