Introduction
Represents a basic concept of:i. Electric energy harvesting.
ii. Green energy
Project purpose: to generate electricity from energy loss ofvibrating motorized machine.
A concept of vibration is applied in PIZEGE, to transfer thekinetic energy from the vibration to electric energy.
PIZEGE design represents a basic model to harvest thekinetic energy created from the vibrating motorizedmachine which is then transferred and stored as electricenergy.
10% to of the electricity can be saved from the amountgenerated by UTP

Objective
To harvest energy loss from motorized vibrating
machines (Case Study: Compressor)
To save electricity cost by at least 2% per week
(Case study: one wing of lecturers office).
To promote the concept of energy harvesting

Piezo-electric
Piezoelectric element is now widely used to harvest
mechanical energy and convert it to electric energy.
Basically, piezoelectric element produces electric
energy when the material is stressed or pressure is
applied on it. Lead-zirconate-titanate (PZT) is commonly used in
producing this piezoelectric device.

Previous Design
Efficiency:
Amount of Piezo-disk used on previous prototype is
very few and not compatible to use for more Piezo-disk as the current prototype and it is waste of space.

Economic Considerations
Electricity usage at one wing of lecturersoffice (Third floor of each block) based
on Tariff B, Low Voltage Commercial
Tariff.
No Description Value obtained
1 Total penda flour light in one wing = 110 tubes
2 One penda flour bulb produce = 36 W
3 One wing penda flour bulbs produce = 3.96 kW
4 Total working hours in a week = 40 hours
5 Amount of power produced = 158.4 kWh
6 Low voltage commercial tariff = 0.393 RM/kWh
7 Total charged amount for a week = RM62.258 One piezo produce = 0.3 V
9 Total 9 piezo produce = 2.7 V
10 Ratio to commercialize product = 25
11 Commercialized product produce = 67.5 V / 10 A
12 Saved power = 27 kWh
13 Amount saved per week = RM 10.611
14 Percentage saved per week= 17 %

Recommendation
Use Piezoelectric Energy Harvesting Power
Supply [LTC3588]
Increase amount of Piezo-disk for a larger
scale of machine (e.g. compressor)
Need more sensitive Piezo
