There is a huge amount of interest among our community in wearable electronics, but it is fair to say that it is a technology that has a way to go at our level in terms of its application. Some twinkly LEDs are all very well, but unless you have the arrived-on-a-spaceship-from-the-future aesthetic of someone like [Naomi Wu] to carry them off they get old rather quickly.
What the sew-on LED sector of wearable electronics is waiting for are some applications, wearable lights that do something rather than just look pretty. And [Moko] has a project that takes them in that direction, with her color organ dress, a garment whose LEDs react to ambient sound with the aid of a MEMS microphone and an Adafruit Gemma M0 microcontroller board. The LEDs form a color wheel which rotates, and stops at a point proportional to the sound level at the time.
The write-up is an interesting one, going into a little detail as it does in the images on the construction of an electronically-enhanced piece of clothing. Wiring everything up is one thing, but there are other considerations such as the incorporation of extra panels to protect them from mechanical stress, and from sweat. From a dressmaker’s perspective it’s a well constructed garment in its own right with an attractive PCB-style pattern (Where did she get that fabric? Or did she print it herself?) and it appears that she’s the fortunate owner of a serger (overlocker).
Well-assembled clothing has made it here before, for example an impressive jellyfish skirt or this laser-cut arcsin dress. And should you wish to make a garment for your next wearable project, you’ll be sure to need a well-stocked textile bench.
Using sewing simulation, 3D modeling and laser-cutting [Nancy Yi Liang] makes custom dresses that fit like a glove. Her project documentation walks us through all the steps from the first sketch to the final garment.
After sketching the design on paper, the design process moves into the digital domain, where an accurate 3D model of the wearer is required. [Nancy] created hers with Make Human, a free software that creates to-size avatars of humans from tape-measured parameters. Using the professional garment modeling software MarvelousDesigner (which offers a 30 day trial version), she then created the actual layout. The software allows her to design the cutting patterns, and then also drapes the fabric around the human model in a 3D garment simulation to check the fit. The result are the cutting patterns and a 3D model of the garment.

Even in this age of wearable technology, the actual fabric in our t-shirts and clothes may still be the most high-tech product we wear. From the genetically engineered cotton seed, though an autonomous machine world, this product is manufactured in one of the world’s largest automation bubbles. Self-driving cotton pickers harvest and preprocess the cotton. More machines blend the raw material, comb it, twist and spin it into yarn, and finally, a weaving machine outputs sheets of spotless cotton jersey. The degree of automation could not be higher. Except for the laboratories, where seeds, cotton fibers, and yarns are tested to meet tight specifications, woven fabrics originate from a mostly human-free zone that is governed by technology and economics.

The once successful Kickstarter and National Science Foundation (NSF) research grant winner Electroloom is saying “Thanks and Farewell” to its backers, supporters, and sponsors. The startup ran out of funding while developing printer-like machine that uses electrospinning to automatedly produce ready-to-use garments.
Electroloom has been an ambitious project to explore if electrospinning could be made viable for garment manufacturing. The process that uses a high voltage to transform a resinous liquid into non-woven fabric was originally invented for textile fabrication, although its low throughput has always been a limiting factor. The method was mostly used in laboratory and medical applications. In 2014, Electroloom began developing a process that would bring the technology back to its fibrous roots, building an amazing prototype machine that could print an entire shirt in one piece. Electroloom’s Kickstarter campaign was funded in 2015, and earlier this year, an NSF research grant was awarded to the startup.
