Researchers from Belgium have devised a plan for making headway into the area of flexible, washable electronics. These integrated electronics, which could be incorporated into clothing and biomedical applications, require all connections between components to stretch like rubber bands while maintaining their conductivity.
These are being designed at the TFCG Microsystems Lab at Ghent University.
Here's a bunch of cool pics from their website.
