Program#

Introduction (10 min)#

  • Why soft, why embedding

What is electricity? (15 min)#

  • What is a circuit
  • How does electricity move
  • Voltage, Resistance, Current
  • LEDs

Conductive materials (10 min)#

  • Fabrics - resistive/conductive
  • Threads - resistive/conductive
  • Inks - resistive/conductive

Tools (10 min)#

  • Vinyl cutter, laser, embroidery, machine sewing
  • Multimeter, soldering iron

Hard/soft connections (10 min)#

  • Machine-sewable Hard/Soft Connections
  • crimp beads
  • Perfboard/Conductive thread
  • Metal machine popper/Conductive fabric
  • Hand sewable metal popper/Conductive thread
  • Wire/Conductive fabric (soldering)
  • Wire/Conductive thread (soldering)

Soft sensors (35 min)#

  • Digital
  • Switches - momentary/toggle
  • Tilt
  • Joystick
  • Stroke
  • Analog
  • Pressure sensor ( analog input example)
  • Potentiometers
  • Stretch sensors - fabric/knit
  • Bend sensors
  • Accelerometer

Programming (60 min)#

  • Intro to microcontrollers and board computers
  • Connecting to the microcontroller
  • Reading code
  • Sensor circuits
  • voltage dividers
  • pull up/down resistors
  • Normally on/off LED - how to switch that in the code
  • Tips for making data meaningful

Learning outcomes#

  • Understand how we can produce soft circuits, sensors and actuators
  • Learn how to embed them in garments, soft objects or wearables
  • Study and learn soft-hard connections
  • Discover necessary materials, components, tools
  • Explore and replicate existing projects
