چکیده انگلیسی
In this paper a novel multimodal hybrid bridge energy harvester (HBEH) using combined piezoelectric and electromagnetic conversion is reported. The architecture, fabrication, and characterization of the harvester is discussed. The devised HBEH consists of a permanent magnet, a wound coil, a piezoelectric plate, an airfoil, and two cantilever beams attached to a base support frame. The upper cantilever is holding a permanent magnet and an airfoil as tip mass. A piezoelectric plate is bonded on this beam near its fixed end. On the other hand, the lower beam holds a wound coil. The coil is adjusted in such a way that it is in-line and close to the permanent magnet. The harvester is capable of converting bridge vibrations and ambient wind energy into useful electrical energy to operate wireless sensor nodes (WSNs) for the health monitoring of bridges. Experimentally, the HBEH operated at three, low frequency resonant modes, ranging from 11 to 45â¯Hz, concentrated around 11, 38 and 43â¯Hz. Moreover, under sinusoidal base acceleration of 0.6â¯g, the harvester produced a maximum power of 2214.32â¯ÂµW across a matching impedance of 28â¯Î© from its electromagnetic portion at 1st resonance (11.1â¯Hz). However, a peak power of 155.7â¯ÂµW was generated by the harvester from its piezoelectric part under 0.4â¯g base excitation across 130â¯kΩ load resistance. Furthermore, at 6â¯m/s pulsating wind speed, the harvester generated load voltages of 25â¯mV and 114â¯mV from its electromagnetic and piezoelectric portions when connected to optimum load impedance of 28â¯Î© and 130â¯kΩ respectively.
