有了这款纹身 触碰皮肤就能接电话 Researchers have created temporary tattoos that are sensitive to touch and can be used to control electronic devices like smartphones. Working in collaboration with Microsoft Research, researchers at the Massachusetts Institute of Technology’s (MIT) Media Lab produced the temporary tattoos, which are called DuoSkin. Using gold leaf, the temporary transfers can be used as touch sensitive trackpads or to transmit information to a smartphone. For example, swiping left or right on the tattoo could be used to scroll through an album of pictures. “These tattoos enable anyone to create interfaces on their skin,” explains Cindy Hsin-Liu Kao, a PhD student at the MIT Media Lab. The conductive gold leaf design acts as the interface, and is hooked up to small electronic components to transmit the data to the computer. A second application is for output displays on the skin, which can change color or pattern based on changes in temperature, or as Kao claims, even changes in emotion. Using thermochromic* pigments*, which change color in response to fluctuations* in temperature, conducted by the gold leaf. The tattoos can also be used as communication devices to transmit data, such as near field communication (NFC)* tags — the same technology used in smartphones to transmit data from one device to another without touching.
