Open Circuit by Christoph Haag, Martin Rumori, Franziska Windisch & Ludwig Zeller:

A silent labyrinth created out of open copper trails on the floor carries the electrical signals of a multichannel sound repository. By putting wireless speaker-cylinders on them, the carried soundlayers become audible and the interpretation by the visitors is made possible. The “Offene Schaltkreis” reacts depending on the way how the speakers are used: if nothing is moved, the sounds stay calm and soft, but as soon as a single cylinder is placed elsewhere, the sounds of all speakers intensify simultaneously. This results in a dynamic relation between silence and noise, which is influenced by the visitors. 

Copper Foil Tape wth Conductive Adhesive – 25mm x 15 meter roll – Copper tape can be an interesting addition to your toolbox. The tape itself is made of thin pure copper so its extremely flexible and can take on nearly any shape. You can easily solder to it, and the tape itself can carry current just like a wire. On the back is an electrically conductive adhesive. The adhesive can’t carry significant current but it is very handy for sensing applications where you don’t want to solder the copper tape.

We’ve seen such tape used for EMI shielding, working with EL, making capacitive touch pads, ultra-thin wiring needs, etc.

Comes in a roll 15 meters long, this tape is 3mils/0.07mm thick, 1″/25mm wide and has conductive adhesive on one side and a protective paper backing over the adhesive.
