A recent research project using a capacitive sensor tomeasure water levels comprises two PCB (printed-circuit-board) plates placed one in front of the other at a controlleddistance. Every plate ...

Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting, ultracapacitors ...

There are many applications which require pulse power. The needed burst of energy is derived by rapidly discharging a previously charged capacitor. As the energy stored in a capacitor is equal to ...

Part 2 goes further into the methods that can help lower EMI in switched-cap designs, including implementation of active EMI filters and visible light communication. Part 2 delves further into why ...

Experts believe their dream of clean energy storage is a step closer after they unveiled their ground-breaking super-capacitor technology that is able to store and deliver electricity at high power ...

As digital still cameras (DSCs) and mobile phone cameras become more popular, users are demanding higher-quality photos under lower-light conditions. The popular Xenon photoflash is excited by high ...

The batteries we rely on for everything from our cars to our cell phones use a chemical reaction to store and release an electrical charge. The chemicals involved force a large number of tradeoffs in ...
