Basic Rules to Remember RULE #1: ELECTRONS ARE LAZY

RULE #2: ELECTRICITY HATES WASTE

RULE #3: CIRCUITS ARE A SYSTEM


TWO

SOFT CONDUCTIVE MATERIALS


Materials Fabrics Conductive E-Textiles

Semi-Conductive E-Textiles

Threads and Yarns

Inks and Tapes


Materials Cont. Metal Accessories Snap Buttons

Beads

Conductive Hook & Loop Tape

Hook & Eye Latch

Zippers


How to use materials to make circuits?

Conductive Fabric

Traces

Conductive Threads Conductive Inks & Tapes

Snap Buttons Hook & Eye Latch

Hard to Soft Connections Metallic Beads Zippers


Important Rule Isolating Traces:

Always cover the knots (intersection between traces) with fabric, hot glue or nail polish!

Electronically Speaking: Avoid Short Circuits!


THREE

SWITCHES


Momentary Switch/ Push Button It stays open as long as it is pressed. The pressing brings the two conductive materials in contact.

FOUR

SENSORS


Soft Sensors Soft sensors are made by changing the resistance of the material.

Resistance Changing

Distance
