Whether it be programmable tattoos, a skin-based input system, or a skin cell gun that can regrow damaged areas in days, there’s a new and exciting technology that is either available or currently being developed. Continue reading to see them all.

3. Programmable Tattoo

Sure, we may be years away from developing the technology required to create programmable tattoos, but that hasn’t stopped moodInq from showing us how they might work. Simply put as possible, “the moodInq system is a breakthrough in tattoo technology, using a skin-safe proprietary E-ink encapsulated pigment system that lasts a lifetime but can be configured to display any design (or none!) to suit your mood.” So how does it work? Moodinq partnered with leading physicians and technicians in the cosmetic surgery industry to implant the E-ink grid, called a canvas. The canvas can go anywhere on your body and be configured to the size and shape of the body party you’d like to ink. After a short healing period (usually 2-3 days), you can begin using the moodInq software included with your kit to change your canvas to display the tattoo you desire!

2. Skinput

Skinput is a new skin-based touch user interface, “based on an armband straddling the wearer’s biceps and detecting the small vibrations generated when the user taps the skin of his arm.” It’s great for games, especially Tetris. Due to different bone densities, tissue mass and muscle size, unique acoustic signatures can be identified for particular parts of the arm or hand (including fingers), allowing people to literally control their gear by touching themselves.

1. Skin Cell Gun

Unlike other medical devices used to treat burn victims, this groundbreaking skin gun by Jorg C. Gerlach and colleagues at Stem Cell Systems GmbH in Berlin uses “individual adult stem cells from the patient’s uninjured skin are applied to the wound site, where they differentiate into normal skin.” The newly introduced stem cells are able to regenerate and differentiate into their respective parts in a matter of days. The first phase of gathering the patient’s stem cells, creating a solution, and applying the stem cells takes approximately 1.5-2 hours. Within a week, the wound dressing procedure allows the stem skin cells to fully generate normal skin, and after a couple of months the skin regains its color and texture.
