    HISTORY

    The idea ofnanotechnology was bornin December 29, 1959when physicist RichardFeynman gave a lectureexploring the idea of

    building things at theatomic and molecularscale.

    Richard Feynman.

    WHAT IS NANOTECHNOLOGY?

    Simply stated, it is theworld of the very small

    things, such as moleculesand atoms.

    NANOGENERATORS

    y Ananogenerator is any nanoscale device used togenerate power. Alternatively, a nanogeneratormay be any generator that uses nanoscale tools,

    like nano wires, to generate electricity.

    . In this work, we present a direct-write technology toProduce and place piezoelectric PVDF nanofibers at

    the same time with the in-situ poling and mechanicalstretching process simultaneously as the foundation fornanogenerators .

    FABRICATION PROCESS OF THE NANOGENERATOR

    . First, two aluminum electrodes areput on the plastic substrate

    The aluminum electrodes serve as thecollector for piezoelectricity

    measurement.

    Secondly, we directly write PVDFNanofiber across two grounded

    aluminum electrodes using theN

    FES

    process.

    Finally, silver pastes are applied the two ends ofPVDF nanofiber sothat the bonding between nanofiber and electrodes are reinforcedand the contact resistance is reduced.

    ADVANTAGES AND POTENTIAL APPLICATIONS:

    The piezoelectric nano generator could potentially

    convert the following into electric energyfor self-powering nano devices and nano systems:

    mechanical-movement energy, such as body or

    muscle movement or blood pressure;

    vibration energy, from acoustic or ultrasonicwaves; and

    hydraulic energy, such as from the flow of bodyfluids or blood, the con-traction of blood vessels,or dynamic fluid in nature.

    HOWMUCH ENERGY A PERSON CAN GENERATE?

    The average person's body could, theoretically, generate

    100 watts of electricity using a bio-nano generator. However, thisestimate is only true if all food was converted to electricity, and the human body needs some energy consistently, so possiblepower generated is likely much lower. The electricitygenerated by such a device could power devices embedded in thebody (such as pacemakers), or sugar-fed nanorobots.

    Mechanical Energy

    our body produces:

    Blood flow: 0.93watts

    Exhaling: 1.00

    watts

    Inhaling: 0.83

    watts

    Walking: 67.0

    watts

    Electrical Energy

    available from our

    body:

    Blood flow: 0.16 watts

    Exhaling: 0.17 watts

    Inhaling: 0.14 watts

    Walking: 11.4 watts

    New nanotechnology electrodes

    could generate electricity at lowercost than solar arrays

    Astudy published in the American

    Chemical Society's journal NanoLetters reveals that thermocells basedon carbon nanotube electrodes mighteventually be used for generating

    electrical energy from heat discardedby chemical plants, automobiles andsolar cell farms
