Conventionally, frequency tuning is achieved by changing the capacitance of a tank using varactor. However, it is more power efficient to minimize the capacitance of the tank and adjust the inductance for frequency variation. Therefore, the need for a variable inductor arises.A novel integrated vari.....

Electrorheological(ER) fluids are of high interest because potentially they can provide simple, quiet, and fast interfaces between electrical controls and mechanical systems. However, a problem with ER fluids to date is that the yield strength is too low for many practical applications. The main dra.....
