Long-time readers of my site no doubt know of my fascination with the field of 3D printing and tracking the advances that are made almost weekly to this technology. From simple plastic tchotchkes to replacement parts to materials that few ever dreamed would be used, 3D fabbers are fast becoming an integral part of manufacturing at all levels of complexity. A few months ago researchers at Lawrence Livermore National Laboratory published the results for a revolutionary 3D printer called the Optomec Aerosol Jet 500, a fabber which uses a range of nanomaterials as its feedstock. To cut to the chase …

Just last year around this time the company MC10 figured out how to fabricate small networks of sensors built out of flexible circuitry that stick to the skin of the wearer and collect biotelemetry. By sticking a single square of wavy, flexible circuitry someplace on your person you could keep a medical team appraised of certain aspects of your health. The tech curve, as always, moves like a roller coaster gone out of control... in the journal Nature Nanotechnology a research team at the Swiss Federal Institute of Technology improved upon the design and created flexible circuitry tattoos that can …
