Section snippets
Evolving technology of miniature power harvesters
Miniature power harvesting is the process of generating minute-scale electricity from external energy sources such as solar, thermal, wind, vibration, and chemical sources, human body heat, human movements, and so on. The main motivations for minute power harvesting devices are to add simplicity and ease in daily life, lower cost, and respect the nature of ecosystems. Besides, ambient energies and radiation can be a great solution as they are ecologically friendly and renewable. Also, in this
Positive prospects of micro-scale electricity harvesters
Micro-scale power harvesters such as thermoelectric, thermo-photovoltaic, piezoelectric, and microbial fuel cell are very useful for easy powering or charging of mobile electronics, even in remote areas, without the need for large power storage elements. Besides, such energy scavenging devices also encompass several extra benefits that may attract more attention to their systems viability as described in Fig. 1.
For instance, the thermoelectric generator utilizes unused, ambient, or human body
Challenges and constraints of minute-scale power generators
Currently, wireless on-chip scale electronics technology is more frequently demanded due to its smaller size, portability, and most importantly longevity. Thus the capabilities of such microelectronics devices, especially those with onboard power harvesting ability, are very convincing. However, the reliability of the devices is still uncertain. This is, of course, due to their complete dependency on adjacent natural energy supplies, whose presence has some limitations. For examples, solar
Analysis of energy conversion performances
The improvements and modifications made to power harvesting devices are the key points leading towards higher impact energy transduction mechanisms. The developed systems must have a strong energy conversion ability, which is usually known from the output power produced. In this section, competences achieved by each enhancement methodology for the miniature power harvesters are gathered and analyzed, contributing to a performance comparison for the decade of 2005–2014. Moreover, the highest
Remarkable breakthrough achievements
This study has investigated the optimized performances of four types of micro-scale energy harvesting devices: thermoelectric, thermo-photovoltaic, piezoelectric, and microbial fuel cell, during the last decade. The breakthrough achievements gained according to the previous section’s methodological performance analysis are indicated in Table 1. The materials or strategies applied and advantageous or key elements are listed in Table 1 in conjunction with their corresponding results.
According to
Conclusions and recommendations
The methodological performance analysis presented in this review indicates positive responses for all the four types of energy harvesting microdevices. They use reliable ambient energy sources and simple operating mechanisms, achieve faster energy transduction, having good life-times and embedding abilities, and are smaller in size. Substantively, the SnSe single crystal may be among the new viable thermoelectric materials due to its higher measured ZT value in comparison to Bi2Te3 and Sb2Te3
