Heart-powered pacemaker could one day eliminate battery-replacement surgery
A new power scheme for cardiac pacemakers turns to an unlikely source: vibrations from heartbeats themselves.
UK scientists develop optimum piezoelectric energy harvesters
Scientists working as part of the Metrology for Energy Harvesting Project have developed a new model to deliver the maximum power output for piezoelectric energy harvesters.
All-carbon-nanotube transistor can be crumpled like a piece of paper
Study reveals switching mechanism in promising computer memory device
(PhysOrg.com) -- Sometimes knowing that a new technology works is not enough. You also must know why it works to get marketplace acceptance. New information from the National Institute of Standards and Technology ...
Boiling breakthrough: Nano-coating doubles rate of heat transfer
By adding an incredibly thin coating of alumina to a metal surface, researchers at the Georgia Institute of Technology have doubled the rate that heat travels from a solid surface such as a pot on a stove into ...
Virtual ghost imaging: New technique enables imaging even through highly adverse conditions
Ghost imaging (GI), and its even more oddly named cousin virtual ghost imaging (VGI), seem to contradict conventional wisdom by being able to image an object by simply counting photons in a "light bucket." This non-intuitive ...
New 'soft' motor made from artificial muscles
The electrostatic motor, used more than 200 years ago by Benjamin Franklin to rotisserie a turkey, is making a comeback in a promising new design for motors that is light, soft, and operates without external electronic controllers.
New nano-material combinations produce leap in infrared technology
Arizona State University researchers are finding ways to improve infrared photodetector technology that is critical to national defense and security systems, as well as used increasingly in commercial applications and consumer ...
Powering pacemakers with heartbeat vibrations
Sick hearts may help to keep themselves beating longer with a device that could harvest energy from heartbeat-induced chest cavity vibrations.
Researchers uncover transparency limits on transparent conducting oxides
Researchers in the Computational Materials Group at the University of California, Santa Barbara (UCSB) have uncovered the fundamental limits on optical transparency in the class of materials known as transparent ...
Flaky graphene makes reliable chemical sensors
Scientists from the University of Illinois at Urbana-Champaign and the company Dioxide Materials have demonstrated that randomly stacked graphene flakes can make an effective chemical sensor.
Light makes write for DNA information-storage device
Researchers have demonstrated a write-once-read-many-times information-storage device, made of DNA embedded with silver nanoparticles, that uses ultraviolet light to encode data.
Graphene's piezoelectric promise
Engineers predict that graphene can be coaxed into acting piezoelectric, merely by punching triangular holes into the material.
Demonstration of ultra-high speed piezoelectric thin film with nanodomain structure
The Japan Synchrotron Radiation Research Institute, Tokyo Institute of Technology, the National Institute for Materials Science, and Kyoto University confirmed for the first time in the world that it is possible to achieve ...
