4 Crafty Ways to Make DIY Sewable Electronic Sensors 

# data[].attributes.attachment_link.readable_text
Creating your own sensors for e-textiles, soft circuits and wearables is a uniquely creative way to dive a bit more into the inner workings of sensors and switches. In addition to being a relatively inexpensive alternative to pre-manufactured sewable electronics pieces, DIY sensors and switches offer customization and design opportunities for student projects that require only a trip to a local craft or hobby store. Read on for our four favorite techniques.

1. Sewable Snaps as Switches

One easy way to add a customized on/off switch to a project is sewing in a snap with conductive thread in place of a LilyPad Slide Switch.

SparkFun carries a Snap Assortment that works well with our needle sets and projects.

Tips for selecting a snap for your project:

Verify that it is made out of a conductive material; plastic snaps or coated metal snaps will not work.

Check that the sewing spaces are large enough to accommodate the needle you or your students will be using.

Test the snapping function - are the snaps easy to snap together and apart?

Watch Feldi, a SparkFun Creative Technologist, construct a circuit with snaps in this video (snap project begins ~2:51):
For more information on how switches work and building projects using snaps, check out these resources:
2. Magnetic Clasps as Switches

Another great way to experiment with crafting temporary attachments and switches is to try out magnets. Magnetic snaps (often found in the accessory and purse/bag making aisle of craft stores) and magnetic clasps (found in the jewelry aisle) offer two interesting ways to prototype: they can operate as a switch or a way to add modular components to a project.

SparkFun carries 18mm Magnetic Snaps, which we found work well in projects.

Tips for selecting a magnetic clasp for your project:

Verify that it is made out of a conductive material and has no insulating coating.

Pull test the clasp - are the magnets too strong or will they pull apart your project or stitching?

Choose a clasp that will be easy to attach to - will a needle and thread fit through any holes or loops on it and make a good connection to the conductive surfaces?

Here's an example of an LED in a crochet flower made modular with magnetic jewelry clasps:

For more information on adding magnets to your project, check out these resources:

3. Zippers as Switches and Sensors

Using a zipper as a sensor is a way to augment an existing interaction you may already have with clothing and wearables. There are a few ways to create both digital and analog sensors out of zippers, which we first saw documented by Joo Youn Paek in a class called Sensor Workshop at NYU's Interactive Telecommunications Program (ITP). Both techiques require using a zipper with a metal zipperhead and/or metal zipper teeth. Sew or attach conductive material along opposite sides of the zipper, and the sides are connected when the zipper head stops across them, providing a path for current flow.

Here's an example of a zipper as a switch I built as part of a soft circuit techniques "scrapbook." This project also uses snaps so that the sensor can be detached and another used in its place. Zipper switches can be used for simple circuits or as input to a microcontroller.

Tips for selecting a zipper for your project:

Verify that the zipper head is made out of a conductive material and has no insulating coating; all-metal zippers are a nice option as well.

Opt for a wide-tooth zipper - it will make stitching conductive thread in between the teeth easier.

Test zipping action - is it easy to activate for your user?

These connected DJ Hoodies from Kobakant use a variety of custom sensors, including zipper sensors, to select one of four filters to apply to an audio sample channel during a live performance.

4. Metal Beads for Simple Tilt/Motion Sensors

To add simple motion sensing to a project, you can craft a tilt sensor using a conductive material such as conductive fabric, aluminum foil attached with iron-on interfacing, or thick embroidered patches of conductive thread as contact points. Then use conductive thread and a metal bead or conductive pom pom that will touch the patches as it moves around and complete a circuit at each contact point. These sensors can be used in simple circuits (to turn on LEDs at each patch) or as inputs to a microcontroller.

A tilt sensor example made with a metal bead, conductive thread and conductive fabric. When the bead touches the patches, the LEDs light up:

Tips for creating a tilt sensor for your project:

Make sure the conductive bead will touch all of the conductive patches on the project, measure and prototype before final construction.

Opt for a wide-tooth zipper; it will make stitching conductive thread in between the teeth easier.

Test zipping action - is it easy to activate for your user?

The Masai Dress from Studio 5050 is a beautiful and fashionable implementation of a motion sensor out of beads and conductive fabric integrated into the design of a garment. The conductive thread and bead sensor trigger sound clips that create a unique soundscape as the wearer moves.

e-Textiles Course Design

Description

Digital data is being infused throughout the entire physical world, escaping the computer monitor and spreading to other devices and appliances, including the human body. Electronic textiles, or eTextiles, is one of the next steps toward making everything interactive and this page introduces my efforts to assist students with the first steps of developing their own wearable technology devices.

This coursework is somewhat of an extension of my volunteer work in the eTextiles domain, detailed here, but the materials on this page were developed largely on my own and for different audiences: (1) a 2 hour workshop on simple parallel circuits on textiles for 7th graders and (2) a month-long winter term course for undergraduates.

Documentation

Lesson Plan for 2 Hour eTextiles Workshop for 7th graders. This workshop was held in April 2017 as part of the Stanford SPLASH "Education by Students for Students" weekend. Parts of this lesson plan can be repurposed for the first week of the winter term course on eTextiles.

Draft Syllabus for a One Month Undergraduate Course on eTextiles. This class will be held in January of 2018. This sample syllabus is a work in progress.

7th Grade Student Evaluations from 2-hour eTextiles Workshop

What are the 2 most exciting things you learned in today's eTextiles lesson?

What questions do you still have?

How can this lesson be made better?

1. Sewing skills.
2. Current in textiles.

What sort of crazy eTextiles have been made!

If students speed things up

* That there is conductive thread.
* How to sew things together

* How to program LEDs.
* How to sew things other than LEDs in a circuit.

Very interesting and cool! Though - doesn't really need to be improved.

* That you can use the thread to make a circuit.
* Also a way to tie the thread.

Do not know yet.

Nothing

* Sewing.
* Testing out if it works.

None

more time for each step.

1. If the threads touch the circuit will short circuit.
2. that there are threads for making electronic circuits.

Can we program some thing like this

Textile Messages focuses on the emerging field of electronic textiles, or e-textiles - computers that can be soft, colorful, approachable, and beautiful. E-textiles are articles of clothing, home furnishings, or architectures that include embedded computational and electronic elements. This book introduces a collection of tools that enable novices - including educators, hobbyists, and youth designers - to create and learn with e-textiles. It then examines how these tools are reshaping technology education - and DIY practices - across the K-16 spectrum, presenting examples of the ways educators, researchers, designers, and young people are employing them to build new technology, new curricula, and new creative communities.

Actualmente, existen en el mercado diferentes plataformas de desarrollo que están adaptadas específicamente para trabajar con textiles o materiales flexibles como proyectos multidisciplinares, especialmente proyectos artísticos y artesanales DIY, o enfocados al mundo de la ropa interactiva y los e-textiles. hilos conductores de electricidad. Las más populares son LilyPad y Flora, que son compatibles o basadas en arduino. Estas placas tienen un gran potencial educativo para desarrollar las competencias del siglo XXI, y acercarnos, por ejemplo, al internet de las cosas. Ambas plataformas, gracias a la forma que tienen los pines, su reducido tamaño y bajo consumo se utilizan para el desarrollo de

En este post voy a hablaros de la plataforma de hardware libre LilyPad arduino . Esta placa fue creada por la ingeniera, educadora y diseñadora Leah Buechley . Como argumento en mi tesis doctoral ( Capítulo 2.2.1 : E-textile toolkits, Web 2.0 y la liberación de los circuitos), Buechley diseñó esta placa de bajo coste, inspirada por las teorías del construccionismo de Seymour Papert y con el objetivo de democratizar el campo de la computación ubicua. Para ella, la computación es una herramienta de empoderamiento, y considera que es un tema de vital importancia que todos los usuarios tengan control sobre la tecnología. Un dato muy interesante, es que esta placa fue diseñada primeramente con el objetivo de explicar a jóvenes audiencias, especialmente mujeres, cómo construir textiles electrónicos, tendrá también una gran acogida por parte de la comunidad de artistas y diseñadores.

Imágen obtenida de la entrevista a Leah Buechley: Crafting the Lilypad Arduino. Make Magazine

Esta placa, que distribuye Sparkfun Electronics , tiene forma de crculo y ha ido sufriendo mejoras desde que se lanzó en 2007, por lo que en el mercado nos podemos encontrar diferentes modelos que varían según su funcionalidad. Así, en función al proyecto que vayáis a realizar podéis elegir entre varios modelos de LilyPad arduino.

Cualquiera de estos modelos te permite crear prototipos e interactuar con sensores ,controlar LEDs o motores. Como explico en esta entrada, en el mercado existe una amplia diversidad de componentes extra ( sensor de luz, buzzer , sensores de temperatura, ...) que han sido adaptados para ser incluidos fácilmente en textiles. Como señalo, estas placas y los componentes se pueden lavar, bajo ciertas condiciones.

Generalmente, utilizo para mis proyectos Lilypad ATmega328V. Esta placa tiene 14 entradas/salidas digitales (de los cuales 4 pueden utilizarse para salidas PWM y 6 entradas como analógicas) y un botón de reinicio.Debajo os dejo el esquema:

Y un ejemplo de un proyecto práctico utilizando LilyPad ATmega328V y el enlace al tutorial:

Ahora bien, si os queréis iniciar a esta plataforma otra opción, es adquirir la o la LilyPad Arduino Simple Board LilyPad Arduino USB ATmega32U4 que son muy similares a excepcion de la última tiene un puerto USB en lugar de los headers para FTDI. Estas placas anque tiene menos pines de la placa que os cito arriba, tienen la ventaja de que ambas se pueden alimentar a través de una batería LiPo de 3,7V que te permite un voltaje de 3,3V. Aquí os dejo el enlace a un tutorial de inicación a Lilypad Arduino utilizado la Simple Board.

En función del proyecto, os puede salir económico adquirir el kit contiene LilyPad Development Board o laLilyPad ProtoSnapque además de la placa diferentes accesorios y módulos electrónicos c omo un sensor de luz, un buzzer o un sensor de temperatura para hacer todo tipo de proyectos de tecnología vestible. Si aún os quedan dudas, antes de comenzar, os aconsejo que le echéis un vistazo a la guía que propone la experta en e-textiles Angela Sheehan. Tambien , que os leáis la versión castellana de libro Open Softwear.

Si iniciaros con estas placas os resulta difícil, porque no sabéis o no quereis programar, otra buena práctica es comenzar con los kits LilyPad Sewable Electronics Kit o LilyMini ProtoSnap que incluyen microcontroladores Attiny ya preprogramados.

Por otro lado, de un tiempo a esta parte existen también otras modelos de Lilypad que se han diseñado para realizar proyectos específicos. Por ejemplo, para realizar un descargar el código en proyecto que incluye sonido o música en textiles, os recomiendo utilizar LilyPad MP3 que es compatible con los esquemas escritos para el MP3 Player Shield. La placa se puede alimentar con una batería Lipo de 3,7V o con una fuente externa entre 3.5-6V, y os podéis Github.

Para realizar un proyecto que requiera comunicación inalámbrica o wireless, os recomiendo LilyPad XBee. En este tutorial creado por Luiz Zanotello se explica muy bien como iniciarte al uso de esta placa.

Para diseñar y desarrollar proyectos en el ámbito de IOT (Internet de las cosas) os recomiendo Lilypad Simblee BLE board. Esta placa te permite conectar tu teléfono móvil por Bluetooth Low Energy (BLE, ou Bluetooth 4.0) a los diferentes dispostivos electrónicos de tu proyecto. Además, consume muy poca energía y viene con un conector JST para conectar una batería LiPo. Si queréis conectarlo utilizando un conversor Série-USB, teneis que utilizar el FTDI de 5.5V. No es necesario desarrollar la app.

Aquí podis echarle un vistazo a un tutorial diseñado por la experta en e-textiles Angela Sheehan.

Para terminar esta entrada, os dejo el link a al tutorial y un video que recopila varios proyectos realizados con esta plataforma.
