Wearable computing is all the rage this year as Google pulls back the curtain on their Glass technology, but some scientists want to take the idea a stage further. The emerging field of stretchable electronics is taking advantage of new polymers that allow you to not just wear your computer but actually become a part of the circuitry. By embedding the wiring into a stretchable polymer, these cutting edge devices resemble human skin more than they do circuit boards. And with a whole host of possible medical uses, that’s kind of the point.

A Cambridge, Massachusetts startup called MC10 is leading the way in stretchable electronics. So far, their products are fairly simple. There’s a patch that’s meant to be installed right on the skin like a temporary tattoo that can sense whether or not the user is hydrated as well as an inflatable balloon catheter that can measure the electronic signals of the user’s heartbeat to search for irregularities like arrythmias. Later this year, they’re launching a mysterious product with Reebok that’s expected to take advantage of the technology’s ability to detect not only heartbeat but also respiration, body temperature, blood oxygenation and so forth.

The joy of stretchable electronics is that the manufacturing process is not unlike that of regular electronics. Just like with a normal microchip, gold electrodes and wires are deposited on to thin silicone wafers, but they’re also embedded in the stretchable polymer substrate. When everything’s in place, the polymer substrate with embedded circuitry can be peeled off and later installed on a new surface. The components that can be added to stretchable surface include sensors, LEDs, transistors, wireless antennas and solar cells for power.

For now, the technology is still the nascent stages, but scientists have high hopes. In the future, you could wear a temporary tattoo that would monitor your vital signs, or doctors might install stretchable electronics on your organs to keep track of their behavior. Stretchable electronics could also be integrated into clothing or paired with a smartphone. Of course, if all else fails, it’ll probably make for some great children’s toys.
