A B S T R A C TThis paper reviews the energy harvesting for micro level devices such as mobile phones, low powered signal lights and energy storage batteries by using Lead Zirconite Titanite (PZT) with the help of vibration on cantilever beams and batteries. Recent advances on micro power portable devices require limitless battery life for improving performance. A lot of energy is being wasted which is around us and also research has been conducted to develop energy harvesting devices by using PZT materials. This paper gives innovative ideas to develop energy harvesting devices for future scientific community.

The present-day consumer is looking for durability, and comfort in apparel. Sewing is the most used technique to convert two-dimensional fabric into 3-dimensional apparel. Seam performance is an important factor to achieve the durability and comfort of the apparel. Seam efficiency depends not only on sewing parameters but also on fabric type. Ideal combinations of both are important to achieve perfect seam performance and efficiency. How different fabrics perform to specific sewing parameters were reviewed.
