“…In case of tire pressure monitoring system (TPMS), the vibration is distributed over the frequency range from 100 to 1000 Hz with quite high acceleration [39]. Similar high frequency application environment is available from aerospace vehicles during their take-off and landing [40]. The reported devices can be useful under such circumstances for harvesting useful electrical energy.…”

JOURNAL OF MICROELECTROMECHANICAL SYSTEMS 1 High Figure of Merit Nonlinear Microelectromagnetic Energy Harvesters for Wideband ApplicationsDhiman Mallick, Andreas Amann, and Saibal Roy, Member, IEEE Abstract-We report a new approach for designing highperformance microelectromechanical system (MEMS) electromagnetic energy harvesting devices, which can operate at low frequency (<1 kHz) over the ultrawide bandwidth of 60-80 Hz. The output power from the devices is increased significantly at a low optimized load and this overall enhancement in performances is benchmarked using a "power integral (P f )" figure-of-merit. The experimental results show that the efficient nonlinear designs produce large P f values, giving rise to one of the highest normalized P f densities among the reported MEMS scale nonlinear energy harvesting devices. This improvement is achieved by suitably designing the nonlinear spring architectures, where the nonlinearity arises from the stretching strain of the specifically designed fixed-fixed configured spring arms under large deflections and gives rise to wideband output response. Different fundamental modes of the mechanical structures are brought relatively close, which further widens the power-frequency response by topologically varying the spring architectures and by realizing the same using the thin silicon-on-insulator substrate using MEMS processing technology. In addition, we have used the magnet as proof mass to increase the output power in contrary to conventional approach of using the coil as the proof mass in micro-electromagnetic energy harvesters. The high performance obtained from the MEMS energy harvesters with integrated double layer micro-coil is compared with the same using wire wound copper coil. The experimentally obtained results are qualitatively explained by using a finite-element analysis of the designed structures.[2016-0038]

“…Because aircrafts flying at high altitudes are subject to large thermal gradients, the use of TEGs to power wireless SHM sensors for aerospace applications is a field of interest. Pearson et al [12] investigated using piezoelectric materials and TEGs to harvest ambient vibration and thermal gradients, respectively, present on aircraft. Simulation results utilizing temperature data taken from thermocouples placed at various positions on an aircraft ( Figure 12) yield peak Figure 12: Locations of thermocouples used for the TEG power output simulation [12].…”

This paper reviews recent developments in energy harvesting technologies for structural health monitoring applications. Many industries have a great deal of interest in obtaining technology that can be used to monitor the health of machinery and structures. In particular, the need for autonomous monitoring of structures has been ever-increasing in recent years. Autonomous SHM systems typically include embedded sensors, data acquisition, wireless communication, and energy harvesting systems. Among all of these components, this paper focuses on the energy harvesting technologies. Since low-power sensors and wireless communications are used in newer SHM systems, a number of researchers have recently investigated techniques to extract energy from the local environment to power these stand-alone systems. Ambient energy sources include vibration, thermal gradients, solar, wind, pressure, etc. If the structure has a rich enough loading, then it may be possible to extract the needed power directly from the structure itself. Harvesting energy using piezoelectric materials by converting applied stress to electricity is most common. Other methods to harvest energy such as electromagnetic, magnetostrictive, or thermoelectric generator are also reviewed. Lastly, an energy harvester with frequency tuning capability is demonstrated.
