Why have contacts that just help you see? According to Google, the company is developing a smart contact lens that's "built to measure glucose levels in tears using a tiny wireless chip and miniaturized glucose sensor that are embedded between two layers of soft contact lens material."
The Google Cultural Institute gathers international collections and exhibits from museums as well as archives worldwide (including, yep, works of Salvador Dali), and brings them to anyone with an Internet connection. Price tag: your soul (just kidding, it's free).
A digital microphone that would be tattooed into the user's throat is another invention Google potentially wants to develop. The patent (which Google acquired via a Motorola Mobility subsidiary) describes a wireless device that is able to transmit the sound of a user's voice to devices like smartphones.
This isn't your typical Times Square billboard. Patented by Google in 2008, this sensor, once placed in a smartphone, could read temperature, light, humidity, sound and the chemical composition of the air around it. Ads would then change based on those readings.
Not satisfied with having a robot army of destruction, Google also wants those robots to be smart. Hence their research into machine and artificial intelligence which, among other things, has been able to learn how to play all those classic 80s video games.
