Creating Cathodes for Air-Breathing Biobatteries
Posted in Electronics, Batteries, Electronic Components, Power Supplies, Medical, Features, MDB on Wednesday, 01 May 2013
Devices that support various functions of our bodies are being used increasingly. Today, they include cardiac pacemakers or hearing aids. Tomorrow, they may be contact lenses with automatically changing focal length or computer-controlled displays generating images directly in the eye. But, none of these devices will work if not coupled to an efficient and long-lasting power supply source. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences (IPC PAS) in Warsaw say that the best solution seems to be miniaturized biofuel cells that consume substances naturally occurring in the human body or in its immediate surroundings.

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.

Self-Charging Power Cell for Small Devices
Posted in Bio-Medical, Electronics, Batteries, Electronic Components, Power Supplies, Medical, Briefs, MDB on Friday, 01 February 2013

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.
