    The following institutions have funded our research and supported our work:

    From 2013-2015 Mika is a guest professor at the eLab at Kunsthochschule Berlin-Weissensee

    From July - December 2013 Hannah was a researcher at the UdK's Design Research Lab

    From 2010-2012 Mika was a guest researcher in the Smart Textiles Design Lab at The Swedish School of Textiles

    From 2009 - 2011 Hannah was a graduate student in the MIT Media Lab's High-Low Tech research group led by Leah Buechley


    In 2009 Hannah and Mika were both research fellows at the Distance Lab


    Between 2003 - 2009 Hannah and Mika were both students at Interface Cultures

    EMF amplifier

    EMF (Electro Magnetic Field) is all around us, but we do not see or hear them. By amplifying it with EMF amplifier, you can listen to them.

    Many artists work with EMF amplifiers in their artistic expressions. One can also use E-Textile techniques to make soft textile antennas and create wearable EMF listeners.

    In E-Textile Summercamp 2016, Afroditi Psarra and Martin De Bie lead a workshop on this topic introducing few method/circuit to amplify EMF around us.

    Inspired by their workshop, we made EMF listener jacket and cape using conductive thread and fabric as antennas. Here is the circuit we used from Martin’s fabric EMF amplifier circuit.
    EMF circuit schematic

    Here is the original circuit layout from Martin

    and it will look something like this when built (the circuit in the photo is not finished)
    EMF fabric cirucit TO92

    This can be made with TO-92 package transistors, but you can also use SMD transistors to make it flat and small. For EMF cape, it is made with SMD transistor soldered directly on Karl Grimm copper conductive thread and couched on fabric button.

    To build the EMF circuit, you will need
    -2N3904 NPN transistor x4
    -2N3906 PNP transistor x1
    -Audio Jack x1

    Then you can use conductive textile materials something like these to build the fabric PCB. If you do not have the exact material, you can improvise with other types of conductive textile materials.

    -Silver Stretch conductive fabric coincell battery holder
    -Karl Grimm copper conductive thread
    -Metal gimp Cuivre-Brass conductive thread (Antenna)
