May 12th 2015, 3 hour workshop at the RCA Information Experience Design department in London, UK

This workshop is only open to students of the university.

A three-hour introductory workshop to materials, tools and techniques for actuating textiles.

This brief workshop will start with an introductory overview to electronic-textiles, explaining materials such as conductive threads and fabrics, magnet wire, nitinol (a shape memory alloy) and thermochormic pigment. After demonstrating examples of different kinds of electronic textile actuation, students will proceed to build their own actuators.

The two different kinds of electronic actuation explored in this workshop are:
– Electromagnetism (motors, vibration movement, sound)
– Heat (melting/softening, thermochromic pigment/colour-change, SMA/muscle-wire/nitinol)

thermochromic pigment/colour-change

Using heat to actuate thermochromic pigment. Thermo = temperature, chromic = colour –> temperature actuated colour change!
