  title={Microfibre–nanowire hybrid structure for energy scavenging},
  author={Yong Qin and Xudong Wang and Zhong Lin Wang},
A self-powering nanosystem that harvests its operating energy from the environment is an attractive proposition for sensing, personal electronics and defence technologies. This is in principle feasible for nanodevices owing to their extremely low power consumption. Solar, thermal and mechanical (wind, friction, body movement) energies are common and may be scavenged from the environment, but the type of energy source to be chosen has to be decided on the basis of specific applications.
