Also, other wears embedded with piezoelectric devices have been experimentally used. Shoes embedded with piezoelectric devices have been popular these days enabling the user to charge the accessories during walk. Two train stations in Japan have tested piezoelectric floor which powers to the station’s doors. How much you would dance if dancing can power your house? In London, a dance club uses piezoelectric flooring system which produces energy to operate the lighting and different equipment in the club by the steps taken by people on the floor. The use of piezoelectric devices has taken the next step by its use in energy harvesting in large scale. Furthermore, they have been used as sensors, sonar detector and producer, actuators, etc. Research on self-powering vehicles using piezoelectric devices is going on. They are also used in piezoelectric microphones where sound wave produces a reverse piezoelectric effect and hence the waves are detected. The piezoelectric devices are used in the lighters in which a hammer hits the device to produce high voltage current to set a spark and ignite the fuel. Research activities have been carried out to increase the production of electricity in a significant amount. The use of piezoelectric devices in order to produce electricity is increasing though its low efficient production has put a barrier for the use. Apart from this, there are various organic polymers (polyvinylidene fluoride /PVF 2) which exhibits piezoelectricity far greater than quartz crystal.
occur naturally whereas barium titanate, lead zirconate titanate, lithium niobate, potassium niobate, lanasite, bismuth ferrite, zinc oxide, etc. Piezoelectric materials like quartz, berlinite (AlPO 4), sucrose, Rochelle salt, Topaz, lead titanate, etc. Since mechanical losses in our daily life are inevitable, efficiency enhanced piezoelectric devices can be a better solution to decrease the exploitation of energy. Piezoelectricity has been popular these days because modern people are motivated to decrease energy loss for tackling the energy crisis in future. However, the most popular use is in gas lighter and spark plugs. Nowadays these devices are used in smart wears, sensors and different solar cells, for increment of efficiency. The discovery of these devices is as old as the thermoelectric devices dated, the 19 th century. The electric polarization can create charge just as in solar cells. Piezoelectric devices are those devices in which pressure or mechanical stress can generate electricity since change in electric polarization is caused due to strain. Piezoelectricity means the electrical energy acquired from the mechanical stress provided on the piezoelectric devices.
