Tyagi, A., Tripathi, K. M. & Gupta, R. K. Recent progress in micro-scale energy storage devices and future aspects.
In this chapter, we show the model of micro-scale energy harvesting system and research efforts both in designing low-power efficient hardware platforms and in creating software components to operate micro-scale energy harvesting systems at their maximum potentials.
Flexible integrated micro-scale energy storage has attracted increasing research interest due to numerous compelling device applications.
Flexible micro-scale energy storage devices as the key component to power the flexible miniaturized electronic devices are attracting extensive attention.
While this enables us to prolong the lifetime of a wireless sensor network (perpetually), the realization of such sustainable micro-scale energy harvesting system is challenging due to the unstable nature of environmental energy sources and demanding requirements of applications.
We highlight the need of deployment study of micro-scale energy harvesting systems in addition to designing and operating research and propose middleware architecture for a unified structured way to optimize energy harvesting system performance.
With the DBS model, we can first offer a physical interpretation on macro-scale regime transition via the shift of global minimum point of micro-scale energy dissipation from one potential trough to the other.
Table 1 shows several micro-scale energy conversion devices [71].
In the suggested framework, the Helmholtz free energy and the dissipation energy at the macro scale are equaled to the volumetric average of the Helmholtz free energy and the dissipation energy at the micro scale.
Despite of that, since in mixing, specially at micro scale, is also important the energy needs to run the microdevice, an average input power coefficient, which takes into account the power needs both to run the channel and to pitch the square cylinder, has been also calculated.
