Row energy.
History of energy harvesting.
small sensors .
It is The technique of converting the raw energy source into useful electrical energy that is what we call energy harvesting.
These systems are often very small and require little power
The history of energy harvesting dates back long time ago people use of windmill to mill grain and the waterwheel to pump the water .

Why do we need this technology
Most low-power electronics, such as remote sensors and embedded devices, are powered by batteries. However, even long-lasting batteries have a limited lifespan and must be replaced every few years. The replacements become costly when there are hundreds of sensors in remote locations. Energy harvesting technologies, on the other hand, provide unlimited operating life of low-power equipment and eliminate the need to replace batteries where it is costly, impractical, or dangerous.
Most energy harvesting applications are designed to be self-sustaining, cost-effective, and to require little or no servicing for many years. In addition, the power is used closest to the source, hence eliminating transmission losses and long cables. If the energy is enough to power the device directly, the application or device powered by the energy can operate battery less.

Major challenges
As more flexible and low-cost light harvesting devices emerge, embedded integration of battery-less sensors that function particularly on harvested energy into luminaires will become an important challenge. In addition, controlling lighting systems reliably based on sensing information from energy harvesting wireless sensors will be another technical challenge.
