2. INTRODUCTION
Energy harvesting sources including
solar, wind and thermal each with a different
optimal size. They either waste much available
energy due to impedance mismatch, or they
require active digital control that incurs
overhead, or they work with only one specific
type of source. No more research on the
vibration domain
3. PROPOSED SYSTEM
This paper has investigated the optimal power that can be
extracted from ROAD SPEED BRAKER over a wide
speed range using electromechanical vibration conversion
from human movement. Driven by the potential to power
small portable electronic devices, more recent research in
energy harvesting from ROAD SPEED BRAKER has
focused on
1) increasing the power output
2) energy harvesting from the motion of vehicles.
10. EXPLAINATION
mechanical stability of the piezoelectric transducer
under large mechanical stress
Piezoelectric transducer plate is kept at the bottom of
the speed breaker, so when the vehicle passes through
speed breaker on the spot it compresses and produces
pressure which is then used to produce electricity.
11. APPLICATIONS
Long lasting operability
No chemical disposal
Cost saving
Maintenance free
No charging points
Inaccessible sites operability
Flexibility
Applications otherwise impossible
