Electric virus powers liquid crystal display in piezoelectric breakthrough

Scientists at the Lawrence Berkeley National Laboratory have developed a means of converting mechanical energy into electrical energy using a harmless, specially engineered virus. By simply tapping a finger on a virus-coated electrode the size of a postage stamp, the scientists were able to produce enough current to drive a liquid crystal display, albeit a very small one. The scientists claim that this is the first time that the piezoelectrical properties of a biological material have been harnessed.
