Northwestern researchers create Rubber-Band Electronics

Scientists foresee a time when medical monitoring devices are integrated seamlessly into the human body, able to track a patient's vital signs and transmit them to his doctors.

Graphene supercapacitor breaks storage record

Researchers in the US have made a graphene-based supercapacitor that can store as much energy per unit mass as nickel metal hydride batteries - but unlike batteries, it can be charged or discharged in just minutes or even seconds. The new device has a specific energy density of 85.6 Wh/kg at room temperature and 136 Wh/kg at 80 °C. These are the highest ever values for "electric double layer" supercapacitors based on carbon nanomaterials.
