Class 10: Wearables II#

Global Instructor: Liza Stark

This second class on the topic of wearables and e-textiles will provide a more advanced coverage on soft sensors and actuators.

Program Outline

  • Introduction (10 min)
  • What does it mean to be wearable? What factors and variables must we take into consideration?
  • (Show projects related to agenda)

  • Actuators (70 min)

  • What are different types of outputs? How do we control them? What are transducers?
  • Visual
  • LEDs
  • Neopixels
  • Optical fibers
  • Thermochromic ink + heated circuit/code
  • Sound
  • Fabric speakers + amplifier circuits/code
  • Motion
  • Shape memory alloy + high load circuit/code
  • Flip dot
  • Flapping wing
  • Mini vibration motors
  • Powering circuits

  • ATtiny (35 min)

  • Intro - miniaturizing, pinout, etc
  • Programming the ATtiny
  • Touch/sensor circuit (the same one I did at the workshop)
  • Sound circuit with stretch sensor

  • Wireless (35 min)

  • RF, EMF circuits
  • Antennas

  • eTextile Tools (10 min)

  • Why create tools to support your practice
  • Pin probes
  • Continuity testers
  • Measuring resistance

  • REFERENCES

  • actuators

Assignment

  • Document your idea , sketches, references and research
  • Create a swatch using an attiny with one input and one output of your choice, using hard-soft connection solutions and battery
  • Create 2 actuator swatches. Test them with the Arduino or ATtiny.
  • Learn how to program and ATTiny , add the libraries and links you used for your code
  • Document the schematic and the programming code, libraries you had to add and calculations
  • Upload a small video of your object working
  • EXTRA POINT : Integrate it to a project
