In electrical circuits that drive lasers, run cardiac implants, or convert between alternating and direct current, components called capacitors produce large, fast pulses of energy. A new composite ...

Direct-current triboelectric nanogenerators arising from electrostatic breakdown can eliminate the bottleneck problem of air breakdown in conventional triboelectric nanogenerators, offering critical ...

The new capacitor is much smaller than a conventional device. (Courtesy: Nanyang Technological University) Researchers in Singapore have developed a prototype polymer capacitor that can store much ...

Recently, it has been suggested that the energy density in metal-dielectric-metal (MDM) capacitors could be significantly increased if the gap spacing between the electrodes is reduced to a nanometer ...

Engineers designing power electronics find that capacitors are needed for several functions, from energy storage to filters and decoupling. Different capacitor types are available, that at first sight ...

While capacitor versions have not changed much, there are a number of new power applications, where they are now used, such as alternative energy, electric vehicles (EVs), energy storage and more.
