ECOSECURITY ENERGY HARVESTING THROUGH FOOTSTEPS

USING PIEZOELECTRIC STANDARDS

Ecological security is an important basis of the entire human security

system. Since Industry revolution, human began to suffer from many kinds

of pollution and ecosystem degradation, such as air pollution, water

pollution, soil loss and degradation, etc. The need to generate electricity is

the demand for todays life because of the fact that even if the planet doubles the amount of solar and wind power available, there would still be a shortage

of clean electricity. Comparison of different forms of commercial power

generation by use of the fuel cycle methods developed in European studies

shows that the health burdens are extreme in areas where power stations

(based on coal, Ignite, and oil) are situated as they pollute the outdoor air to

large extent therefore one has to overcome this state. The Proposed work

approaches in a direction to overcome the above said problem by utilizing

the pressure produced by footsteps for generation of electricity using IEEE

SA 176-1987, as this standard is a withdrawn so the same work can be

proceeded using EN 50324-1:2002 (Piezoelectric properties of ceramic

materials and components - Part 1: Definitions and classifications),

EN 50324-2:2002 (Piezoelectric properties of ceramic materials and

components - Part 2: Methods of measurement and properties - low power) ,

EN 50324-3:2002 (Piezoelectric properties of ceramic materials and

components - Part 3: Methods of measurement - high power).

The idea behind selecting IEEE SA 176-1987 Standard was that it

determines Elastic, Piezoelectric and Dielectric constants which are the core

properties of the work it also shows crystallography applied to piezoelectric

crystals and wave and vibration theory. EN 50324-1:2002 has been chosen

as it has wide application in transmission of signals in communication

electronics, EN 50324-2:2002 can have widely differing shapes and may be

employed in a range of vibrational modes .The polycrystalline nature of

ceramics, statistical fluctuations in composition and the influence of the

manufacturing process, result in specified material coefficients being typical

mean values. These values are provided for design information.

EN 50324-3:2002 standard relates piezoelectric transducer ceramics for

power application over a wide frequency range both as electromechanical or

mechanoelectrical converters.

Piezoelectric materials can bring revolutionary change in the World of

Electricity as it works on the principle of Pressure and generates electricity.

Piezoelectric effect can be implemented in crowded areas like Bus Station,

Railway Stations, Malls and Footpaths of Metro-Politian cities by utilizing

the pressure created by footsteps to generate electricity. Water pressure

developed through tubewell and waterfall can also be utilized to vibrate the

piezoelectric crystal.

The Aim of project is to develop electricity at low cost. The working is

based on the concept of capturing the unused energy, surrounding any

system and converting it into electrical energy that can be used to extend the

lifetime of that system by providing energy through backup. The

piezoelectric plates will be placed under the non-conducting material

(graphite marble) and the pressure created by the footsteps will produce

energy which can be stored and utilized as mentioned.
