Project SAKALARAVA
Added Apr 23, 2014 | Rate View top rated
SAKALARAVA is a device which converts the energy generated from mechanical vibrations of an engine to electrical energy. The vibrations of the engine of a light motor vehicle are captured and amplified by a thin cantilever shell made up of aluminum. The vibrations at the tip of the cantilever are monitored and absorbed by latest technology piezoelectric film which acts as a dynamic-strain-gauge. This was designed (using CATIA V5 software) and fabricated. Results have shown that for one millimeter square area of the piezoelectric film attached to the device generates a peak voltage of 137microvolts. Incidentally, the sound energy can also be captured by having a sound absorbing layer, although it is not quantified in this current work. The model generates a maximum output of about 0.3V continuously throughout the entire working of the engine, which will be further amplified.
