Mobile phone battery chargers also use power when the mobile phones are not being charged. The majority of power is wasted if the battery charger remains connected to the mains. Most consumers do not realise this and keep their chargers connected to the socket all the time.
It would be good to pull the battery charger from the socket. It would be still better to build chargers in such a way that they use no or a negligible amount of electricity after completion of the battery loading process. Some manufacturers aim at achieving this goal.
In order to establish a general rule for cost reduction, energy efficiency and climate protection, the European Union published the Ecodesign Directive. This directive regulates power consumption for energy-using products. In Germany the directive is implemented by the Energy-using Products Act (EuPA).
The BAM Federal Institute for Materials Research and Testing as the commissioned body is responsible for providing information on this topic which BAM will be doing at the international radio exhibition. BAM experts will answer such questions as:o Which devices use particularly large amounts of energy?

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.
In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...
'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.
Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
