These New Temporary Tattoos Let You Create On-Skin Devices

“I think there is no fashion statement greater than being able to change how your skin looks,” says artist/engineer Cindy Hsin-Liu Kao in the video explaining the idea behind the new on-skin interface DuoSkin developed by MIT Media Lab in collaboration with Microsoft Research. DuoSkin‘s wearable tech takes the form of user-designed, gold-leaf temporary tattoos. She goes on to explain that the designers wanted to make DuoSkin‘s technology easily accessible to anyone. The fabrication process “enables anyone to create customized functional devices that can be attached directly on their skin” using graphic design software, a vinyl cutter, and gold leaf

From DuoSkin’s website:

DuoSkin’s three-step workflow. Step 1: (a) Sketching skin circuitry with graphic design software. Step 2: (b) Fabrication, which includes (c) creating stencils of the circuitry, (d) applying gold leaf as the conductive material, and (e) mounting electronics. Step 3: (f) After completing the circuitry, we apply the DuoSkin device to the user’s skin through water-transfer.



DuoSkin allows users to create three types of user interfaces: 1) input on skin through capacitive touch sensing,2) output on skin through thermochromic resistive heating circuitry, and 3) wireless communication through NFC.  (Photo: Jimmy Day)

The tattoos can take one of three forms, input, output, or communication. The input interface is a lot like the user interface we all know, featuring buttons, sliders, and trackpads to control a music or video player, for example; output uses thermochromic pigments that react to the user’s body temperature to produce changing colors giving it a mood ring quality; and communication lets users read data directly off the skin using NFC tags.

The designers wanted their product to be user-friendly and customizable, both aesthetically and functionally, and by making the fabrication process so open, anyone with a desire to create uniquely beautiful devices on their skin, can. In a paper outlining the development and testing of DuoSkin they explain their hope for the tech’s future:

It is our vision that future on-skin electronics will no longer be black-boxed and mystified; but the will converge towards the user friendliness, extensibility, and aesthetics of body decorations, forming a DuoSkin integrated to an extent it has seemingly disappeared.




Letter Writing Meets Big Data in 'Dear Data'

In the world before ours, before our texts, emails, 140-character thoughts, before we could have conversations with long-distance loves during a morning commute, in that world, communication was something different, something more challenging. I’d hesitate to call it more meaningful—there can be meaning in even the shortest hello if we want there to be—but there is something more, let’s call it more purposeful, in the act of communication in a pre-electronic world.

Researcher William Decker describes how reading pre-telecommunication letters “requires acts of imagination and empathy, but even casual attention to their commonplace expressions reveals a sense of space and time different from our own.” To sit, to write, to send your thoughts to someone and wait, patiently, while your letters finds its way, and to play this process out in reverse while you await response requires an amount of purpose that we may have lost in an instant-communication world. But there’s something more to Decker’s statement, the idea that reading this pre-electronic letter writing reveals something unknown to a modern reader. We get a glimpse of something new; words we may not have known, a voice we can’t imagine, a new way of thinking, a different way of seeing. We are experiencing their world through ours, and perhaps even seeing our world slightly differently.

In their new book, Dear Data (Princeton Architectural Press), designers Giorgia Lupi and Stefanie Posavec are seeing their worlds in new ways. The book, a collection of postcards the two sent to each other over the course of a year, explores the very mundane data of our lives: drinking (Week 18), complaints (Week 7), swearing (Week 37), or times we wish for privacy (Week 51), and beautifully visualizes them.

From Dear Data website


As the two write in the book’s introduction, “We would spend the week noticing and noting down our activities or thoughts, before translating this information into a hand-drawn visualization.” Through the process of examining their worlds in new ways, and noting emotions, sounds, and thoughts Lupi and Posavec, like the pre-telecommunication era Decker writes about, reveal a sense of space and time that we’d never considered. Through their weekly postcard exchange the two got to know each other, and themselves. The world around them was data to be collected, to be examined. They continue:

Besides finding data in the world around us, we are all creating data just by living: our purchases, our movements through the city, our explorations across the internet, all contribute to the “data trail” we leave in our wake as we move through life.

Lupi and Posavec’s explorations are alternatively funny (Posavec’s strategy for remembering the animals she spotted on her bike ride ending in a shouted “Give me my PHONE!”) and vulnerable (Lupi’s privacy week postcard, presented as a sort of erasure poem— the absence of words adding weight to the revealed ones), and at all times thoughtful. In an era where our personal data is constantly being amassed, studied, packaged, and sold back to us as ads, initiatives, or motivators there is something very powerful about taking it back. And not just taking it back in the way that wearable technology promises to quantify our lives, but taking it back in quiet, tactile, and let’s not forget, analog ways.

Dear Data is a nice reminder that even in this hyper-technological, ever-connected world, there is a beauty and simplicity in returning to a way of connecting that both roots us to our world and to one another.
