A piezoelectric disc is part of the sound component, suitable for electronic products and small volume, electrical products, such as electronic watches, electronic thermometer, calculator, music cards, remote control toys, watches, cameras, telephones, electronic toys, electronic music doorbell card, home appliances, alarm and reversing device all kinds of sound detection, automatic control system and all kinds of electronic products, warning alarm purposes, can also be used as acoustic sensor voice electronic products.
The piezoelectric disc has common types:
thickness 0.4 mm, thin: thickness 0.2 mm, ultra-thin: thickness 0.1 mm. According to the different shapes, the buzzer can be divided into various special-shaped products, such as round, square, circular, feedback, and so on. Our company has produced. It can satisfy the request of 500HZ-20KHZ with different frequencies.
Another usage is the process of optimum energy harvesting by using piezoelectric sensors pasted on a tile structure.
The generation of electric energy when some load is applied on the sensors depends upon various factors such as the number of the piezoelectric diaphragm, the electromechanical coupling coefficient of the piezoelectric sensors, type of strain applied, piezoelectric strain coefficient, and also on the plan of arrangement. Energy harvester floor tile has been designed for electricity generation. An efficient way has been presented to capture the generated energy and boost it by a converter to get regulated output for charging the batteries of mobile. The complete charge cycle has also been studied for the developed system. The simulation and experimental studies have been successfully carried out. The model design and testing were purely for studying the energy generation and capturing phenomena in an efficient manner. It can be implemented to generate large power by suitably arranging the piezoelectric sensors.
