A Look into the Future – Just for Fun

Sometimes it is just fun to look ahead and wonder what the future will bring. In 2011, there have been some interesting announcements that get the imagination going. Epidermal electronics: engineers at the University of Illinois have developed a temporary tattoo-like electronic patch that mounts directly onto the skin. If you can build skin-mounted electronics [...]

Trends in Ultracapacitors

Ultracapacitors are well suited to replace batteries in many applications. Voler Systems developed such a replacement for a company that makes RFID and wireless technology products.The battery replacement was cheaper with a longer life than a standard battery.

Ultracapacitors, also referred to as supercapacitors or double-layer capacitors, are electrochemical capacitors that have an unusually high energy density when compared to common capacitors. Conventional capacitors have enormous power but store only tiny amounts of energy. Ultracapacitors offer orders of magnitude higher energy storage. Larger ultracapacitors have capacities up to 5,000 Farads as of 2010, and 10 Farad capacitors cost only a few dollars.
