            2.3.3   Energy harvesting
            Taking advantage of different forms of energy, or through strategies of collecting the passage of
            people, cars, differences in salinity, currents of air through small devices, etc., is something that
            should happen in a smart sustainable city. Energy harvesters also provide a very small amount of
            power for low‐energy electronics. Many sensors related to IoT, for example could feed themselves
            the required energy units.

            Role of the technology
            Environmental monitoring or reducing environmental burden of application areas using ICT in SSC
            requires sensing network to collect data used in those areas.
            To  reduce  the  environmental  burden  of  the  sensing  network  itself,  it  is  required  to  lessen
            environmental burden of the sensing devices. Sensing networks generally use an enormous number
            of sensing devices.

            Definition of the technology
            Energy  harvesting  technology  is  the  technology  that  derives  energy  from  the  surrounding
            environment (environmental energy), such as light, vibrations, heat and radio waves, and converts
            it into electricity in order to move sensing devices, process signals and convey data through wireless
            networks without being supplied with electricity from any external sources such as batteries. Using
            environmental energy allows us to save maintenance costs for power cables and the replacement
            of batteries.
            Energy  harvesting  technology  is  composed  of  technology  of  generating  electricity  from
            environmental energy and that of storing the electricity that enables it to be used stably.
