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 Method of Controlling Tiny Devices
Posted in Electronics, Power Management, Medical, News, MDB on Wednesday, 06 March 2013
Electromagnetic devices all require an electric current to create the magnetic fields that allow them to function. But as devices become smaller, being able to efficiently deliver a current to create magnetic fields becomes more difficult. Researchers at UCLA say that they have developed a method to switch tiny magnetic fields on and off with an electric field, instead of the traditional approach of running a current through a wire, which they say could lead to big changes in storing digital information and powering motors in small hand-held devices.

Risk Assessment for Power Supplies to Comply with IEC 60601-1 3rd Edition
Posted in Manufacturing & Prototyping, Custom & Contract Manufacturing, Monitoring & Testing, FDA Compliance/Regulatory Affairs, Electronics, Power Supplies, Power Management, Medical, Features, MDB on Tuesday, 01 January 2013
For medical device OEMs seeking compliance to the 3rd Edition of IEC 60601-1 for their power supplies, what is quite clear by now are the regional dates for enforcement, the required risk management at the medical electrical equipment or system level, the new definitions of Means of Operator Protection (MOOP) and Means of Patient Protection (MOPP), and other differences as compared to the 2nd Edition. What is not clear is how to address these new definitions and requirements. Rather than simply redesigning and resubmitting for 3rd Edition certification, questionnaires and flowcharts that map out the requirements at the device or system level help to minimize the evaluation and redesign at the power supply level. By having the medical device OEM and power supply vendor answer the questionnaire concurrently, deficiencies from the equipment or power supply can be quickly assessed in order to satisfy the requirement.
