Microneedles

London-based company CipherX has created an alternative for those who like tattoos but hate needles and blood. Its microneedle patch works like a stamp and offers a fast and pain-free way to get minimalistic tattoos.

Scientists have developed a microneedle patch that can be self-administered and painlessly deposit a tattoo onto skin in minutes. The technology is proposed for simple medical or animal uses but cosmetic uses are possible in the future.
