Power generation with peizoelectricity

[dhayalanvk]

I read an article that using peizoelectricity , ideas to generate energy from public movements was tried. How far was it sucess? If this is possible , can we generate energy from vehicles movement on roads?

So far, the cost of installing peizoelectric sensors is far greater than the value of electricity generated. But, yes, if it could be cost effective, it could be used in roads.

Thusfar it's more of a novelty than a practical solution to our energy needs. The biggest longterm problem, IMHO, is the lack of mechanical robustness. If you want a device that, by definition, must repeatedly deform to generate a useful voltage, then that device must be extremely resistant to fatigue failure. Ceramics don't offer that, nor do the intricate interconnects that must be maintained in the contacting circuitry. When you start talking about putting it on roadways and other environments with frequent catastrophic damage caused by everyday use, the maintenance cost for replacing failed piezos would be huge.

I know that in Japan, for study purposes, piezoelectric sensors have been installed on tokyo station in high traffic areas to generate electricity. Doesn't generate neither volume or good cost, just study.

They look like regular soft tiles and it generates energy while people walk through them.

Peizoelectricity is a fascinating concept that has been explored in recent years as a potential source of renewable energy. The idea of harnessing the energy from public movements, such as walking or dancing, is certainly intriguing. While there have been some successful experiments and demonstrations of this concept, it is still in the early stages of development and has not been widely implemented on a large scale.

One of the challenges with using peizoelectricity for power generation is the relatively small amount of energy that can be produced from each movement. Therefore, in order to generate significant amounts of energy, a large number of peizoelectric devices would need to be installed in high-traffic areas. This could be a costly and complex undertaking.

As for generating energy from vehicles' movements on roads, there have been some studies and experiments in this area as well. However, there are several technical and logistical challenges that need to be addressed before this can become a viable source of energy. For example, the efficiency of converting the energy from the vehicles' movements into electricity needs to be improved, and the infrastructure for installing and maintaining the peizoelectric devices on roads needs to be developed.

In conclusion, while there have been some successful attempts at using peizoelectricity for power generation, it is still in the early stages of development and has not yet been widely implemented. There are still many challenges that need to be addressed before it can become a significant source of energy. However, with further research and advancements in technology, it is possible that peizoelectricity could play a role in our future energy mix.
