­ 'Plug-and-Play' Biobatteries Generate Power for Weeks

Seokheun “Sean” Choi has developed a “plug-and-play” biobattery that can last for weeks at a time and has the ability to be stacked to improve output voltage and current, depending on how the cells are arranged.

  One of the most challenging things about implementing the Internet of Things (IoT) is powering the sensors. We need measurements of almost every metric in a system so that the processing elements can understand what is happening and provide the most accurate output. That means that there will be small sensors

­ Li-ion Batteries Come in from the Cold

Using the bumpy material in Li-ion batteries has the potential to open up the possibility of using them at extremely low temperatures.

  One of the main drawbacks of Lithium ion batteries is that their storage capability is diminished in colder temperatures. Its a phenomenon that happens with many different types of battery, but Li-ion batteries are the currently the most widely used type of battery, and the applications in which Li-

Figure 1: Windings of a three-phase brushless DC motor are driven in a set sequence

­The first idea that electricity could be used to produce rotary motion originates in the 1740s in experiments by a Scottish Benedictine monk, Andrew Gordon. It took nearly another century before a practical battery-operated version appeared in 1834 and then, through the work of Tesla and others, the ground wa
