Abstract
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.
