Piezoelectric materials convert electrical energy into strain, or vice versa. These materials are used to harvest energy from everyday mechanical vibrations -- such as an air conditioning unit ...

Modulators can be used to convert electrical signals into optical signals. ETH Zurich researchers have presented a new speed record: data transmission with a frequency of over a terahertz. The ...

A resistor’s purpose in life is to convert electrical energy into heat. That’s all it does. Period. But this humble singular purpose can be applied to countless applications, including the termination ...

The purpose of an electric motor is to convert electrical energy into a rotational force that can do work. When appropriate levels of voltage and current are supplied to a motor, it drives the moving ...
