Implantable Silicon-Silk electronics could mean LED tattoos
By Darren Quick
22:52 November 11, 2009 PST
Tattooing dates back to at least Neolithic times and has experienced a resurgence in popularity in many parts of the world in recent years. Advancements in tattoo pigments and the refinement of tattooing equipment has seen an improvement in the quality of tattoos being produced. Today it’s possible to get ink that glows under UV light, but a new technology could see tattoos that emit their own light. Researchers have been able to build thin, flexible silicon electronics on silk substrates that almost completely dissolve inside the body, paving the way for embedded LED tattoos that offer much more than just aesthetic appeal.

Smarter touch surfaces with new pressure sensitive technology
By Darren Quick
01:43 August 28, 2009 PDT
Resistance touch technology, which generally relies on the use of a stylus or similar instrument, typically detects touch by measuring changes in electrical resistance. But it can only detect one touch at a time. Touch screen using capacitance technology can detect multiple inputs, but can’t detect pressure. Now researchers at New York University (NYU) are looking to get the best of both worlds with a new type of touch-sensitive pad that responds precisely to pressure and can detect multiple inputs at once.
