The demand for ever-smaller electronic devices has led to the miniaturization of a variety of technologies, but energy-storage units, such as batteries and capacitors, have lagged behind. Now, researchers at UCLA say that they have developed an innovative technique using a DVD burner to...

Electromagnetic devices all require an electric current to create the magnetic fields that allow them to function. But as devices become smaller, being able to efficiently deliver a current to create magnetic fields becomes more difficult. Researchers at UCLA say that they have developed a method to switch...

Engineers at Cornell have developed a new method of generating terahertz signals on an inexpensive silicon chip, that may be useful in applications such as medical imaging and wireless data transfer. Terahertz radiation, the portion of the electromagnetic spectrum between microwaves and...

Microsemi (Aliso Viejo, CA) has introduced two new non-magnetic, 500-watt transient voltage suppressor (TVS) arrays. The devices were designed specifically for MRI machines to guard against circuit damage caused by electrostatic discharge, electrical fast transients, and the effects of secondary lighting. The...
