Scientific American, 2008
This article explores nanotech machines and says they need a better power source than batteries. The creation of nanogenerators makes power on a tiny scale that may permit the use of waste energy in the form of vibration or the human pulse to power devices. Piezoelectric nanowires could capture the energy to run nanodevices.

Ultrasensitive self-powered cytosensor [PDF]
Nano Energy, 2016 Abstract We developed an ultrasensitive self-powered cytosensor based on biofuel cells (BFC) for the detection of acute leukemia CCRF-CEM cells. The core component of the BFC cytosensor was composed of an aptamer (Sgc8c)-functionalized cathode and a nitrogen-doped graphene/gold nanoparticles/glucose oxidase (NG/AuNPs/GOD) anode, which generated a ...
