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
ASSIGNMENT#
- Build at least one digital and one analogue soft sensors, using different materials and techniques.
- Document the sensor project as well as the readings got using the AnalogRead of Arduino
- Integrate the two soft sensors into one or two textile swatches using hard soft connections
- Document the circuit and it’s schematic
- Document your swatches
- Upload a small video of the swatches functioning
- EXTRA POINT Integrate the swatch into a project
How will it be evaluated?#
- References : tutorial , links, ideas
- Design : program your arduino sketch , design your circuit and schematic
- Fabrication : craft your soft sensors
- Documentation : Anyone can go through the process and understand
- Final outcome : Is the project assembled, functioning and complete
- Originality - Aesthetics : Has the design been thought through and elaborated
Here you can find Liza´s resources on her soft circuiter webpage
