Coffeemaker
This coffeemaker is a newly-arrival of this summer. It is offered in 15 colors (bright yellow, light green, blue-green, peach, light pink, elegant silver, mysterious dark, etc.). Equipped with strength Selector, Coffee Strength Control System, Clock Timer, Drip-stop, Walter-level Indicator and Automatic Shut-off, this high-quality coffer maker can make 10-15 cups of coffee in a short period of 15 minutes. With the Strength Selector you can set this coffeemaker to brew coffee at the strength you like best——from mild to strong. The Coffee Strength Control System clearly indicates at which point the water and coffee ingredients are perfectly balanced. Thanks to the Drip-drop feature you can pour coffee during the brew process, without spilling coffee on the hotplate. Want to wake up to the smell of fresh coffee？ The Clock Timer makes it possible. Own your ideal coffeemaker now!

Nanosize machines need still tinier power plants
By Zhong Lin Wang
The watchmaker in the 1920s who devised the self-winding wristwatch was on to a great idea: mechanically harvesting energy from the wearer’s moving arm and putting it to work rewinding the watch spring.
Today we are beginning to create extremely small energy harvesters that can supply electrical power to the tiny world of nanoscale devices, where things are measured in billionths of a meter. We call these power plants nanogenerators. The ability to make power on a minuscule scale allows us to think of implantable biosensors that can continuously monitor a patient’s blood glucose level, or autonomous strain sensors for structures such as bridges, or environmental sensors for detecting toxins — all running without the need for replacement batteries. Energy sources are desperately needed for nanorobotics, microelectromechanical systems (MEMS), homeland security and even portable personal electronics. It is hard to imagine all the uses such infinitesimal generators may eventually find.
In Brief
★Nanotechnology has huge potential — but those minuscule devices will need a power source that is better than a battery.
★ Waste energy, in the form. of vibrations or even the human pulse, could provide sufficient power to run such tiny gadgets.
★ Arrays of piezoelectric nanowires could capture and transmit that waste energy to nanodevices.
★ Medical devices will likely be a major application. A pacemaker’s battery could be charged so it would not need replacing, or implanted wireless nanosensors could monitor blood glucose for diabetics.
