Tattoos are certainly not for everyone, but if you’re considering one, make sure you know what you’re getting into. This pain chart highlights the parts of the body that can hurt the most when the needle comes down.

Getting a tattoo will hurt; there’s no way around that. However, some parts of the body are extremely sensitive to pain, and only the bravest of brave should even consider tattoos in those zones. This pain chart from Tattoos-Hurt.com explains it all using color, with yellow being the least painful to purple being excruciatingly painful. It’s not surprising that the most painful areas are also considered the most vulnerable areas of the body.

For a general rule, if you’re extremely ticklish in an area, it will probably hurt really bad to have it tattooed. An important thing to consider, however, is the fact that everyone has different thresholds for pain. This chart won’t be spot on for everyone, but it is still effective at giving you a general idea for choosing a location. Just make sure you pick something you really love, or you might end up wanting to cover it up.

Working up a good sweat can be its own reward. But instead of letting all that bodily moisture go to waste, why not let it power your smartphone — via a smart tattoo?

Researchers at the University of California in San Diego, led by Joseph Wang, are wringing more out of sweat — specifically, enough electrical current to potentially power personal electronics while you’re still on the treadmill.

They’ve developed a temporary tattoo sensor that responds to lactate — a byproduct of physical activity, found in sweat and in the bloodstream.

The sensor strips electrons from the lactate, enough to generate an electrical current. That enables doctors to measure lactate levels — but the team also built a bio-battery into the sensor, storing some of the electricity. Read more…
