Wearable electronics

With the aforementioned Google Glass and smartwatches, we’re already seeing this to a degree but it’s going to get way more crazy than that. Smart glasses and smart watches are social devices that connect you to the outside world. There are other wearable electronics in the works that connect you to your body. We’re talking ear buds that measure heart rate,

contact lenses that can measure your blood sugar, temporary tattoos that can unlock doors via NFC technology, and all sorts of cool stuff. Once they work this out for consumer use, it wont’ be long until you start getting options for implants that’ll track your vitals in real time so you’ll know you’re having a heart attack before your heart does. It’s going to save lives.
