“…It indicates that the recent developments are inclined towards generating more power from low frequency and low amplitude ambient vibration with less piezoelectric material. It is apparent that the design proposed by Lam and Salleh [68,69] results in the highest power density per g among others. The normalised amount is computed to be 1085 μW/mm 3 /g.…”

“…The simplest arrangement is a 2-DOF system. Lam and Salleh [68,69] connected the piezoelectric cantilever to the base via an external slotted aluminium beam and recorded 56 mW at 30 Hz. Hong et al [70] harvested a maximum of 7.8 mW at 69 Hz by attaching additional springs at the free end of the piezoelectric cantilever beam.…”

In the past decade, there has been rapid development in piezoelectric energy harvester due to its limited application and low output power. This paper critically reviews the strategies implemented to improve the power density for low-frequency applications. These strategies include piezoelectric material selection as well as optimisations of shape, size and structure. The review also focuses on the recent advances in multi-modal, nonlinear and multi-directional energy harvesting. Based on the comprehensive summary of the normalised power density at 1g acceleration, it was found that most works fell in the second quadrant of low frequency and high power density. The maximum value was around 1mW/mm3 /g. Adding an extension of beam or spring to the conventional piezoelectric beam could enhance the normalised power density dramatically. Additionally, the multi-modal energy harvester exhibits broader bandwidth when its multiple resonance peaks get closer. The findings indicate that the anticipated performance of a piezoelectric harvester can be attained by achieving the trade-off between output power and bandwidth. To achieve high performance at low frequency, the following factors are essential: excellent material characteristics optimised geometry for high strain energy density, excellent flexibility, high excitation amplitude and broad bandwidth.

The aim of this study is to characterise the performance of a Triple Cantilever Hybrid Energy Harvester (TCHEH) based on the triboelectric surface modification. The application is to harvest sufficient amount of power for low power sensor node. The whole system comprises of three separated generators being put together into one prototype with the design of triple cantilever beam. The triple cantilever consists of top and bottom triboelectric energy harvester (TEH) and middle section piezoelectric energy harvester (PEH). The top and bottom section is the Polytetrafluoroethylene (PTFE). The testing for TEH consists of pairing the highest negative charged material which is Polytetrafluoroethylene (PTFE) with few other positively charged materials. The best pair was used for further testing by modifying the triboelectricsurface in order to increase the power output. At the frequency of 13Hz and acceleration at 0.27gms-2 , the ideal opened-circuit voltage, VOC produced for top TEHwas 2.23V and for the bottom TEHwas 2.24V, while for the PEHwas 9.27V. The final prototype of TCHEHproduced an optimum power of 7.29mW at a resistance of 9kΩ. The power density obtained from the prototype was7.36Wm-2 which enable the low power sensor node to power up.

“…Energy harvester is the process of storing energy for a certain time and to be used in wide applications such as medical equipment, electronic devices and other devices. Typically, gadgets, materials or sensors used AC control supplies or batteries to harvest electrical voltages and streams such as piezoelectric generators (PZT) [1], solar powered photograph voltaic cells [2], thermo electric generators (TEGs) [3] and electromagnetic generators [4]. These materials produce an extensive variety of yield voltage and streams [5].…”

The aim of this study is to harvest sufficient amount of power to power up the low power sensor node by using vibration mechanism. The hybrid triboelectric (TENG) and electromagnetic (EMG) nanogenerator is needed to sustain the unlimited usage of energy.The testing for the TENG consisting of varying the air gap distance between the dielectric and the electrode, surface area of the triboelectric layers into a large and smaller surface. Whilst for the EMG, the testing is varying the number of coil turns for each big and small magnet size.At the frequency of 11Hz with the acceleration of 0.69ms-2 , the optimum opened-circuit voltage, VOC produced for TENG is 3.97V while for the EMG is 1.85V. The hybrid nanogenerator produced 2.071mW of power with a resistance of 1kΩ. The power density obtained from the prototype is 2.6059Wm-3 which is enough to power up the low power sensor node.
