M. Amin Karami, PhD


The kinetic forms of energy available in the environment can be transformed to electrical power in large and small scales. The large amounts of power harvested from wind or ocean waves replace fossil fuels and reduce the greenhouse emissions. The small-scale energy conversion can power low power devices and eliminate the need of complicated wiring or repeatedly changing the batteries. The on site energy generation becomes significantly helpful when the devices are very remote (e.g. sensors on bridges) and/or difficult to reach (e.g. sensors inside a jet engine). My research is mainly focused on effective power generation from wasted forms of energy such as ambient vibrations and low speed wind.
