AGENDA

3. Battery size and replacement negating the
size advancement of nanodevices

4. SELF POWERING DEVICE
• A self-powered device that can greatly reduce the size of integrated nanosystems
for optoelectronics, biosensors.

5. METHODOLOGY
ZnO nanowires generates current when vibrated
with ultrasonic waves

6. NANO WIRES
Nanowires shows great promise in creating
future generations of electronic devices

8. WHAT IS A NANOGENERATOR
Nanogenerator is an energy harvesting device
converting the external kinetic energy into an
electrical energy based on the energy conversion by
nanostructure piezoelectric material

9. FABRICATION

10. WORKING
• Nanowires are free to flex with in the gaps
created by the tips of the zigzag electrode

11. MODIFICATION
Too short cannot touch the electrode –Too long cannot
touch the electrode

12. APPLICATIONS
Powers biological sensors
Powers nano devices
Powers small body electronics

13. • Produces 4 watts/cm3 for a single Nanowire
• Millions of Nanowires can produce current which will
optimize operation of Nanogenerator
• Growing on polymer substrates is at very low cost
so that the can be placed into people’s shoes and can
generate electricity while walking
FUTURE SCOPE

15. CONCLUSION
Anything that makes the Nanowire with in the
generator can be used for generating power
It can find more applications in generating small
current to power small body electronics
