Electric Wine
Scientists have extracted electrical power from a grape. The process harnesses the metabolic energy of glucose and oxygen to create a biofuel cell. This is some cheap vino too - only costs a few cents to make. According to Adam Heller and colleagues at U of Texas at Austin, the biofuel cell should also get power from body fluids. It could potentially drive a tiny, autonomous sensor implanted near a wound after surgery to sense fluctuation in body temperature that might signal inflamation and infection. Read more... On a personal note, as the mommy of a three year old who never tells me when she's hurting, I'd like to have a couple of those sensors implanted in two little ears to let me know when there is an ear infection raging - rather than rushing to the Dr.'s office with a perforated ear drum as we did this afternoon!
