It looks like Google Glass was just the beginning . Google now appears to be aiming a few inches lower , working on a temporary electronic tattoo that would stick to the user 's throat . Google-owned Motorola Mobility has filed for a patent , published last week , for a system `` that comprises an electronic skin tattoo capable of being applied to a throat region of a body . '' The patent says the tattoo would communicate with smartphones , gaming devices , tablets and wearable tech like Google Glass via a Bluetooth-style connection and would include a microphone and power source . The idea is that wearers could communicate with their devices via voice commands without having to wear an earpiece or the the Glass headset . And how 's this for future tech ? It could even be used as a lie detector . `` Optionally , the electronic skin tattoo can further include a galvanic skin response detector to detect skin resistance of a user , '' the 10-page document reads . `` It is contemplated that a user that may be nervous or engaging in speaking falsehoods may exhibit different galvanic skin response than a more confident , truth telling individual . '' `` Galvanic '' is a reference to the way some surfaces , even skin , conduct electricity . Google explains mystery barge . In images attached to the filing , the tattoo appears to be between a postage stamp and a Band-Aid in size . The filing says that in addition to sticking via an adhesive to the throat , the tattoo could go on a collar or a band around the user 's neck . Other possible uses include making both incoming and outgoing audio clearer . That could mean anything from making smartphone conversations clearer in a crowded room to being able to listen to music without earphones . And we ca n't quite figure out the use case for this one , but : `` the electronic tattoo can also be applied to an animal as well . '' Digital tattoos and mind-reading headphones . With Google Glass , the company has moved to be at the forefront of the rapidly emerging trend in wearable tech . Glass is a wearable computer with a smartphone-like display that lets users text , browse the Web , take photos and run other apps , all hands free . The latest version rolling out to field testers includes an ear bud , in response to complaints from some that the first version 's bone-conduction sound system did n't work well . It 's not hard to envision the throat tattoo as an eventual answer to that complaint . Other wearable tech either on the market or the horizon includes smartwatches from Samsung and Sony , with Google , Apple and Microsoft expected to join the fray soon . A Motorola spokesman said the company has no comment about the patent filing at this time . YouTube faces backlash for Google+ integration .
Google patent filing paints picture of throat tattoo with microphone . The temporary tattoo would connect with smartphones and other devices . Some have complained about the Google Glass audio system . Wearable tech is an emerging field .
