Power/Performance Bits: April 4


Self-sustaining microbial fuel cell Researchers at Binghamton University developed the first micro-scale self-sustaining microbial fuel cell, which generates power through the symbiotic interactions of two types of bacteria. A mixed culture of phototrophic and heterotrophic bacteria were placed in a 90-microliter cell chamber, or about one-fifth the size of a teaspoon. Phototrophic bacter... » read more

Power/Performance Bits: June 2


Printing RF antennas with graphene ink Researchers from the University of Manchester, together with BGT Materials Limited, a graphene manufacturer in the United Kingdom, printed a radio frequency antenna using compressed graphene ink. The antenna performed well enough to make it practical for use in RFID tags and wireless sensors, the researchers said. Even better, the antenna is flexible, e... » read more
