During the information age architecture has become much more interactive. Designing engaging spaces often involves integrating electric and electronic circuits into architectural elements. In some projects those circuits can affect the overall shape.
Sketching electronics can be part of an architect's design process, made easier by the use of conductive ink which allows you to draw and test your circuits straight away. Bare Conductive Electric Paint is an amazing, quite affordable product with which I have been creating electric doodles on different substrates. As long as you protect the paint from extreme temperatures and from humidity you can flexibly use it in a variety of applications. The patterns composed with the conductive ink can even be so beautiful to become an artwork themselves.
