AsPakistan’s one of the biggest issue is electricity shortfall, generation ofelectricity from fossil fuel is 64%, hydro 30% and nuclear 5% of total, otherrenewable sources like wind, solar and biomass etc. are big players in industry of sustainable energy but smallenergy-harvesting products have their place as well.Generation of electricityusing non-renewable sources  is dangerousfor our environment due to release of dangerous gases like carbon may causerise in temperature and also huge cost. “PIEZOELECTRICITY” is electrical energy harvested from mechanical pressure suchas walking motion. When pressure is applied on an object, a negative charge iscreated on the expanded side and a positive charge is created on the compressedside.

As this pressure is relieved, electric current flows across thesubstance. “Piezoelectricitywas discovered in 1880 by French physicists Jacques and Pierre Curie.”The firstpractical application for piezoelectric devices was sonar, first developedduring World War I.A journey of a thousand miles begins with a singlestep. Energy Floors could make that step more productive. Energy harvestingthrough piezo has potential to replace batteries in small, low power electronicdevices. Many countries like japan, Israel and London are using this method togenerate electricity and fulfill the basic needs of electricity like lightingstreet lamps, airports, terminals and railway stations.

We have already used this method in our semester projectto extract energy from shoes and it was successful we light LED’s using theseelements, so want to use tiles which are consist of piezo elements and whichcan be implemented on public places ,the more people walk the more energy wecan create. Piezoelectric floors then could be able to produce few microwattsand up to watts per step depending on pedestrians and piezoelectric technology.Capacitors could be used to store this energy we could be able to use thatenergy where its required.INNOWATTECH: an Israeli energy harvesting system used thismethod on roads ,every time a vehicle passed by road this converts that wastedmechanical energy into electrical energy and they are generating 200kw per hourof energy, moreover JAPAN havealready installed  this technique indance floors to generate electricity and EastJapan Railway Company (JR East) installed this system in the floor ofbusiest subway station.The total amount of floor-space will add up to around 25square meters, and they expect to obtain over 1,400kw per day ,that is morethan enough to power their systems.
