The article focuses on the significance of microelectromechanical systems (MEMS) and their optical counterparts, micro-opto-electromechanical systems (MOEMS). A novel approach to building microstructures based on nickel has paved the way to lower cost MEM/MOEM applications. Millions of dollars are being invested around the world into developing MEMS and MOEMS technology, and applications as diverse as medical, military, aerospace and home office are already benefiting from it. Three main characteristics making microstructures an important technological development are that systems can be made in a batch process, individual features can be made very small and accurate, and optical elements can be fully integrated. A main advantage of using nickel instead of silicon is that nickel is a much cheaper raw material.
