Development of Samsung EGO / Betiana Pavón

DECONSTRUCTIVE HEADS collection / ALASKA ACCESORIOS
Winner of the contest SAMSUNG EGO Innovation Project / 
Mercedes Benz Fashion Week Madrid
Project by Betiana Pavón / FabTextiles / Fabricademy BCN Student
Betiana Pavon, an Argentinian Accessories designer with her brand ¨ALASKA Accesorios¨ studied at Fabricademy Barcelona in 2018-19.
With her final project she applied to the Samsung Ego Innovation Prize and was selected to present a complete collection for the edition of July 2019 with a prize for development of 10.000 euros!

The project is focused on the design, prototyping and development of "head accessories". Re-referred to as "portable objects", a perfect excuse to crown the head with a distinctive piece, a piece that can be unique, that identifies directly with its user and interacts with it, using Samsung devices as a link.

The project was developed at Fab Textiles Lab in Fab Lab Barcelona for 1,5 month where all looks and custom electronics where designed and fabricated.

As for typologies and morphologies, the concept of “portable structures” is addressed, which can be constructed and deconstructed through modules, achieving almost abstract accessories.

The inspirational axis of this collection is the "Deconstructivist Movement" reflected in organic forms, fragmented, distorted and complex geometries ... product of the incorporation of new technologies (Hardware: machinery, electronics) and computational design tools (Software). The conception of this collection is based on the liberation of geometry and rules in general.

NEW TECHNOLOGIES / PROCESS

3D Print

The computational design allows a new reinterpretation of the forms, in this case applied in portable accessories. By erasing old construction limits, 3D printing allows for the realization of unique, custom-made pieces and contributing to a sustainable digital manufacturing model, where it is produced only on the basis of real demand, thus reducing the waste generated by the fashion industry.



Laser cut

The implementation of new materials (such as acrylic, technical textiles, etc.) and the inclusion of parametric digital patterns that allow the creation of fragmented geometries, distortion and complexity of shapes, require the use of new tools, such as laser cutting. The inclusion of this machinery in the manufacture of this type of parts is key, since it allows perfect finishes, pinpoint accuracy and reduces manual work. Thus achieving in a single step, fast and efficient cutting of pieces and perfect patterns in series.

SAMSUNG DEVICES / INTERACTION INTEGRATION
The main intention of this project is that Samsung devices are not only an addition in the proposed style, but that they interact directly as a link between the carrier and accessories. That is, include technology in the entire project.Runway Mercedes Benz Madrid Fashion Week / July 2019
LOOK 1 / Concentric Hat -Input: Sound vibrations (microphone sensor) -Output: Rhythmic flashing of the lights (neo pixels) integrated in the prototype. Visualization of the sound vibrations received at the moment, on the tablet device.

LOOK 2 / Aurora Cap -Input: The device is connected via Bluetooth using the Android APP "Adafruit Bluefruit". -Output: This APP allows the user to select between 16 million colors, the adjustable brightness of the light source and also use this app to generate their own color light show.

LOOK 3 / Lamp Hat
-The hat contains a custom board, in which a rhythmic code of the LEDs was turned on and off, based on the song of the catwalk, which was saved in ATtiny format. The LED light is channeled and is reflected in the lateral reflectance optical fiber.

LOOK 4 / Parametric Hat
-Input: A webcam incorporated into the accessory records in real time.
-Output: the filming of the runway of the model on the catwalk is displayed on the tablet device

LOOK 5 / Reflecting Hat
-The structure hat formed by a helmet printed in 3D and wing deconstructed parametrically achieved through laser cutting in methacrylate, is assembled and joined through ribbons of reflective material, which reacts to the light of the flashes.

LOOK 6 / Geological Hat
-Input: The device is connected via Bluetooth using the Android APP "Adafruit Bluefruit".
-Output: The user can select the color, but in this case of the neo pixels incorporated in the hat, which in turn are programmed to generate a loop circulation effect pattern around the helmet.

LOOK 7 / Vader Cap
-The user can change the light effects of the built-in LEDs through a button (custom circuit and board). In turn, the light is reflected in the "hair" of fiber optic embroidered by hand in the translucent layer.

Thermochromic research

Thermochromic inks have the property to change color with temperature. In the mid-sixties, laboratories started to develop thermochromic liquid crystal materials. That research emerged at the same time as the first digital watches based on liquid crystal technology.  Nowadays one can find various playful reactive paints like hydrochromic, photochromic, glow in the dark e.t.c.  Instead of using an electric current to change the crystal structure, heat is utilized. We used thermochromic ink with silk screen printing and digital embroidery of conductive thread,  for the creation of garments that are reacting to heat and are ¨ expressive ¨. They charge color as a visual feedback, while providing heat to the wearer. Even though the technology is not new, they create a ¨magic¨ effect and from all our exhibition, where the most popular and comprehensive for the wider public.

Initially the research was the application of thermochromic ink on different types of fabrics : jeans, cotton, neoprene, 3d knitted and synthetic. Different thermochormic inks were tested. The main supplier was SFXC . One can buy directly a paste ready for silk screen printing or the pigment powder and mix it with a base of silk screen binder. The pigments and inks are reacting to different temperatures. If the desired result is to change by the body temperature (passively) the 31°C is fine. If the effect is activated by a heated pad or conductive thread-wires then it is recommended to use a higher temperature , such as 50°C. After various tests, we selected a white neoprene like fabric to apply the silk printed design.

The second part of the project involved testing different conductive -resistive threads to understand how the system works best. For making a heated circuit , the thread needs to be RESISTIVE, so that the current goes through ¨more difficult¨ and it makes the thread heat up. At the same time, it can not be too resistive because it will require a lot of power. We tested threads with different resistance : Karl-Grimm High Flex 3981 (fine copper fiver plied with synthetic fiber core), Karl-Grimm High Flex 3991 Silver 14/000 (fine copper fiber coated with silver plied with synthetic fiber core), Elitex (235/34 polyamide plated with silver), Shieldex (silver plated synthetic thread) and Bekinox VN (fine stainless steel fiber plied).  The two Karl-Grimm and the Elitex threads were difficult to use with the sewing machine and the Bekinox VN was the one that worked the best for use with heat. We order a thread from MADEIRA, a distributor in Spain and the thread arrived the next day!

At the end of this research, we decided to develop a Thermochromiconductive Top* that changes pattern according to conductive threads linked to an Arduino system. The Arduino is connected to a Bluetooth device (Adafruit M0 Feather) which allows one to control the pattern of the dress with a mobile phone. The code implemented in the Arduino produced several heating combinations, such that lines appears in the thermochromic paint, gradually changing the shape of the pattern.

All conductive threads have different properties, the resistance per meter is different in all of them. The ideal conductive threads to build a heating source are made of steel or copper.

Some recommended conductive threads like Bekinox stainless steel thread from Bekaert or Copper thread from KarlGrimm.

The best scenario would be to have a 6-50 Ohm conductive thread with a current of 300-1000 mA flowing through it. The time the thermochromic ink takes to change its color is directly proportional to the amount of current. For 300mA it will need more time than for 1000mA.

To calculate the voltage we just need to use ohm’s law formula:

Voltage equals Current times Resistance or V = I x R

We know our conductive thread resistance(measured with the multimeter), for example 32 ohm, the current has to be a value from 300mA to 1000mA.

For 300mA:

V = 0,3 * 32 => V = 9,6V

For 1000mA:

V = 1 * 32 => V = 32V

Our Thermochromiconductive Top project made us realize that body heat was causing undesirable changes to the pattern. The thermochromic inks we were using were too sensitive, so we decided to remove the conductive threads and create a dress with thermochromic ink only.

Anastasia designed a form-fitting dress with an organic pattern representing the body flow. The model of the dress was conceived on Illustrator and laser cut with the lab Trotec. The motif was screen-printed before assembling and sewing the pattern of the dress.

ID Sound

In 2015 Sonar introduces for the first time the NFC cashless payment system for everything that was sold inside the festival. Each person that atended the festival had one of this tags. IDSound is a critical engineering project that exploits this system and is using the identification data that is stored on these tags to generate a unique sound id for each attendee of the festival. Together with a “smart” glove this system is used for a participative music performance.
