Novel Biological Sources for Implantable Battery Materials
Posted in Batteries, Electronics, Medical, News, MDB on Monday, 23 December 2013
Where will the next source of electrode materials for batteries to power edible medical devices come from? Would you believe, from marine cuttlefish? Researchers at Carnegie Mellon University, Pittsburgh, PA, say that melanin pigments in cuttlefish ink provides the perfect chemistry and nanostructure to power tiny electronic devices that can be either ingested or implanted into the body for applications ranging from biosensing to drug delivery.

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.
