Scaling Up Production of Graphene Micro-Supercapacitors
Posted in Batteries, Electronic Components, Board-Level Electronics, Power Supplies, Electronics, Power Management, Medical, News, MDB on Tuesday, 12 March 2013
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 fabricate micro-scale graphene-based supercapacitors, which can charge and discharge a hundred to a thousand times faster than standard batteries. These micro-supercapacitors, made from a one-atom–thick layer of graphitic carbon, can be easily manufactured and readily integrated into small devices such as next-generation pacemakers, they say.

New Stretchable Battery for Stretchable Electronics
Posted in Batteries, Electronics, Implants & Prosthetics, Medical, News, MDB on Monday, 04 March 2013
Researchers at Northwestern University, Evanston, IL and the University of Illinois have demonstrated a stretchable lithium-ion battery can power their innovative stretchable electronics. The stretchable electronic devices now could be used anywhere, including inside the human body, they say, powering implantable electronics that could monitor anything from brain waves to heart activity. They say that they have demonstrated a battery that powers a commercial light-emitting diode even when stretched, folded, twisted, and mounted on a human elbow. The battery can work for eight to nine hours before needing recharging, which can be done wirelessly.

A hybrid power cell uses a new technique for electrical charge conversion and storage.

Scientists at Georgia Tech say that they have developed a new self-charging power cell technology that directly converts mechanical energy to chemical energy. Then, the power is stored until it is needed to generate electricity. This hybrid generator- storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries, they say.

Li/CFx Cells Enhance Battery Performance in Medical Devices
Posted in Manufacturing & Prototyping, Batteries, Power Supplies, Medical, Products, MDB on Tuesday, 01 January 2013
Contour Energy Systems, Inc., Azusa, CA, introduces its new Lithium/Carbon Fluoride (Li/CFx) primary batteries to be used in medical devices. A proprietary Fluoronetic fabrication technique combines multi-layered carbon nano-materials with new manufacturing processes to achieve long shelf life and wide temperature operation. Contour’s Li/CFx cells are especially well-suited for medical applications due to a relatively flat discharge profile, low internal resistance, and light weight.
