Textiles and Electronics


Sarah and Lara Grant

In this workshop, Sarah and Lara will demonstrate how to create textile sensors and how to integrate these sensors with simple signal processing circuits for controlling sound output. There will also be on hand samples of handmade conductive felt, crocheted stretch sensors, conductive batting and machine-sewn resistors for participants to check out, which will be the focus of this workshop. After discussion of construction techniques and some show and tell, they will walk the workshop through building a simple sound producing circuit and how to connect it to a soft sensor. Participants should also feel free to bring in their own simple circuits in lieu of constructing one with the group.

▓▒░░░Basic Workshop Outline░░░▒▓

Intro to Wearables and E-textiles
- we will briefly go over some projects and visuals of construction to give an idea of the many ways soft circuitry can be utilized.

Intro to materials
- store bought materials that are used for garment construction and other items can be repurposed for use in wearable and soft tech projects, we will go over these and handmade conductive materials, soft switches and variable resistors.
- we have specific techniques that we use and experiment with, we will go over how to make a stitched resistor, a force sensor, stretch sensor and stroke sensor using various soft materials.
- briefly go over examples of stitched circuit traces and needle felted traces

::: we have examples that we will passing around! :::

Build Voltage Control Oscillator circuit
- walk through build of this simple sound circuit and use materials to make your own soft variable resistor. We will be breadboarding this, so no soldering skills are necessary!
- learn about resistance and how to get the output that you desire from taking into account the resistance of your soft variable resistor and the relationship of your fixed resistors and capacitor.

With any time left
- there is so much we want to share, however we do have limited time. If allowed, we will go over how to hand stitch and needle felt circuit traces to sew your electronic components to.

- we would love to answer all and any questions about soft circuitry and the like. We will have materials on hand such as metallic wools, fabrics, threads and conductive felt for you to sample and take home.
- we will also make sure you leave with a printout of the schematic for the VCO circuit and where to buy various soft conductive materials!
