Ring my Bell! Tattoo that vibrates when you get a call

Possible options: (pic: US Patent Office)

Phone maker Nokia has filed a patent for a vibrating tattoo that would alert wearers of incoming calls and texts. As it's actually the magnetic ink that is the vibrating element, it could both be worn as a badge or injected under the skin. The vibrations could be programmed to send other phone related information such as signalling a dead battery and could also have customized "vibe-tones" for different callers, much like custom ring tone today. For people who already feel that they are expected to be constantly on call and electronically available, this may make getting the option of choosing to be disconnected even more problematic.

“I have incredible optimism,” said Stephen Elop, Nokia President and CEO, “because I can see fresh opportunity for us to innovate, to differentiate..."  Certainly, this new technology should set Nokia apart as fresh and innovative.

Meanwhile, I located the following idea for a gadget taking things a step farther (from 2008). It's sobering, yet heady, how fast dreams can become actual technology.  One wonders how long it will be before something similar is developed and becomes the latest hot gadget.
Digital Tattoo Interface Turns Flesh Into An LCD

Imagine this: your phone rings and you lift your sleeve and push a tattooed button on your forearm. Next thing you know there is a digital video of the caller, moving in full video on your arm. After you hang up the tattoo completely fades away to leave nothing but your bare skin.
The Digital Tattoo Interface is a Bluetooth device that is inserted into the skin via a small incision. After inserted as a tube, it unrolls as a flat silicon base. It rests between skin and muscle. Glucose and oxygen in your blood fuel the implant via an attached artery and vein.
A special tattoo on the surface of your skin would interact with the field created by the device. Touching it through your skin would make it react similar to a touch screen display. Implications are limitless. Telephones, TV, the Web and just about everything else we rely on could be literally embedded in your skin."
