2. What is Mechatronics ??
It is combination of
• Mechanical engineering
• Electrical engineering
• Computer engineering
• Control engineering
• System Design engineering

3. The Energy Challenge
1. The world now uses energy at a rate of
approximately 4.1x1020 joules/yr, equivalent to a
continuous power consumption of 13 tera-watts.
• People, accompanied by rapid technology
development and economic growth world-wide, is
projected to produce more than double the demand
for energy (to 30 TW) by 2050

4. Causes for these are
Rapid Technological
Population Growth

5. Fossil Fuel Shortage
Global Warming

6. Pollution

8. Now What is
1. Environmentally friendly
2. Conserves natural resources
and the environment.
3. Clean technology.
4. Currently in beginning stage of it’s development
future will only bring bigger and better things.

9. Goals Of Green Technology
1. Find ways to produce technology in a way that do
not damage or deplete the earth’s natural
resources.
2. Alternative source of technology that reduces fossil
fuels.
3. Demonstrate less damage to animals, humans and
plants.
4. Products can be re-used and re-cycled.

10. 5. Reduce amount of waste and pollution that is
during production and consumption.

11. Solar Powered Circuit
• New technology prepared by scientists from the
University of Pennsylvania.
• Will no longer require a device to
use a battery as the power can come
from light powered circuit.
• Actual creation of stimulated
Human brain.

12. The Terminator However this
technology actually
It is unlikely to think makes that a very
that we would see real possibility
something
like this

13. Working
First difference between this circuit and normal solar cells
Solar cells convert energy to electricity but this breakthrough
involves circuits that provide paths for electricity to flow ~ this
means sunlight absorbed can be directly used to power the device

14. Working
• Surface plasmons (electrons) oscillate on tiny particles
nanoparticles
• Plasmons act as super lenses which gather
light hitting the circuit.
PLASMONS
• Once the light collected the particles pose as electrodes to
ferry away the electricity for device to use.

15. Advantages
• Circuit is very small sized so can be used in various tiny
equipments
• It uses the power of sun to power itself which is the
ultimate source of energy.
• It is purely environmentally friendly.

16. Applications
Touch screen of phone could act as
Both electrical charger and
Computer chip.

17. This breakthrough could
one day make phone
chargers much less
necessary

18. Powering small robotic
devices
Actual creation of
simulated human brain

19. • Artificial neural networks running at ultra fast computer
Calculations.
• Used to setup artificial networks that could model brain.

20. What does Researches Say?
We would have one amp with one volt in a sample the diameter of a human
hair and an inch long ... If the efficiency scaled up without any additional
limits
“This could open the door for many kinds of new devices” – Dawn Bonnell
“The touch screen of your computer could act as both the electrical charger
and the computer chip”-By Dawn Bonnell, a Scientist from the University of
Pennsylvania who co-authored a recent ACS Nano paper describing the
research
“This as the potential to create a new generation of optical and electronic
devices.” –By Lukas Novotny, a Scientist at the Institute of Optics at the
University of Rochester
