Poking Around Textiles With Your Multimeter

Looking for a fun wearable electronics project? While you can buy specific fabric and conductive thread for your projects, sometimes you can even find conductive fabric where you might not expect it!

In this latest video by Adafruit, [Becky Stern] goes undercover at a fabrics store with her trusty multimeter to find some new material that can be used for electronics projects! While pickings are slim, she made some useful discoveries — most metallic fabrics aren’t conductive, but some are — You’ll definitely need to take your multimeter with you.

Another funny quirk is that some fabrics are only conductive in one direction! Which could make for a really cool project that seemingly defies conventional wiring — or you can sew a conductive thread perpendicular to the continuity to connect it all together.

A blanket that detects its own orientation

If you want to capture a 3D model of a physical object, you could use a Kinect, a couple of lasers, constructive light, or even a simple touch sensor mounted on a robotic arm. Those are all expensive devices, and somewhat unnecessary now that you can just throw a blanket over an object and get a 3D model instantaneously.

The project is called IM BLANKY and it’s supposed to reproduce 3D shapes by simply throwing it over an object. The petals in the flower motif are pieces of conductive fabric that serve as contacts for the electrified tassel in the center of each flower. When the blanket is thrown over an object, the tassel is pulled by gravity, makes contact with one of the six conductive petals and sends a tilt switch to a microcontroller.

While we’re not too sure about the resolution IM BLANKY will provide with only 20 tilt sensors, but we imagine this could be used for a few medical applications.

Full fabric soft switches

When we created our backpack strap WiFi detector for Engadget, we embedded soft switches to control the device. They used two sheets of aluminum foil separated by a layer of foam with holes punched in it. [Plusea] has taken a similar approach but has replaced the aluminum foil with conductive fabric. The end result is a set of three soft buttons that can be easily washed. Have a look at the video of it in action below. Check out the followup project that uses the buttons to replace a scroll wheel. Continue reading “Full fabric soft switches”
