We wouldn't blame you if the name VivaLnk didn't instantly come to mind, but you'd probably say "Ohhh, them!" if we tell you that it made Motorola's phone-unlocking temporary tattoo.

The eSkin Thermometer pairs an NFC chip with a temperature sensor that'll tell you how warm your munchkin is in under three seconds. Oh, and it's shaped like a bear, so that's something.
