Developing New Sources of Energy: Self-powered nanogenerator uses body movements to generate electricity, transmit data wirelessly

Taking inspiration from trees, scientists have developed a battery made from a sliver of wood coated with tin that shows promise for becoming a tiny, long-lasting, efficient and environmentally friendly energy source. Their report on the device — 1,000 times thinner than a sheet of paper — appears in the journal Nano Letters.
