Tracking dragonflies on the wing

(PhysOrg.com) -- Duke University electrical engineers have developed a wirelessly powered telemetry system that is light and powerful enough to allow scientists to study the intricate neurological activity of dragonflies ...

New glass stamp may make cheaper, more precise biosensors

Advances in microchip technology may someday enable clinicians to perform tests for hundreds of diseases -- sifting out specific molecules, such as early stage cancer cells -- from just one drop of blood. But fabricating ...

Colored solar cells could make display screens more efficient

(PhysOrg.com) -- A new kind of screen pixel doubles as a solar cell and could boost the energy efficiency of cell phones and e-readers. The technology could also potentially be used in larger displays to make energy-harvesting ...

Mimicking cells with transistors

As the world has become less analog and more digital -- as tape decks and TV antennas have given way to MP3 players and streaming video -- electrical engineers’ habits of thought have changed, too. In the analog world, ...

Catching cancer with carbon nanotubes

A Harvard bioengineer and an MIT aeronautical engineer have created a new device that can detect single cancer cells in a blood sample, potentially allowing doctors to quickly determine whether cancer has spread from its ...
