In the contemporary quest for sustainable energy, potential of piezoelectric energy harvesters to convert mechanical vibrations into electrical has become increasingly important. This study focuses on composites, in particular a BaTiO3/PLA (Barium Titanate/ Polylactic Acid) system with different volume percentages BaTiO3 ceramic particles (20%, 40% and 60%), aim optimizing conversion efficiency. A mathematical model is introduced, encompassing material attributes, loading frequencies...
Chitosan, which is a derivative of chitin, particularly popular due to its biodegradable and renewable nature. However, the properties chitosan can be inconsistent extraction process natural origin, poses challenge use in composite materials as matrix. The tuned by controlling degree deacetylation (the extent acetyl groups are removed from chitin form chitosan) molecular weight. This paper presents detailed study on characterization shrimp shells. structural thermal mechanical were studied...
The growing demand for sustainable and self-powered technologies in automotive applications has led to increased interest energy harvesting from vehicle suspensions. Recovering mechanical road-induced vibrations offers a viable solution powering wireless sensors autonomous electronic systems, reducing dependence on external power sources. This study presents the design, modeling, experimental validation of hybrid energy-harvesting system that integrates piezoelectric magnetoelectric effects...
