As a part of the Engineering for Social Impact workshop by NYUAD, I have visited embroidery workshop in Dharavi Mumbai. Here I’ve met an amazing embroidery machine that will be perfect for eTextile applications.

I asked to insert conductive thread (KarlGrimm silver coated copper) as A thread and to make a coil shape for fabric speaker. The nice thing is that it is very fast to make embroidered fabric speaker (it took them few minute to make one speaker) and the conductive thread gets isolated due to the wrapping thread, so you can make the coil very tight.
