The first ever optical coherence tomography (OCT) images of cubic meter volumes have been produced, through an industry-academic collaboration. The advance could open up many new uses for OCT in industry, manufacturing and medicine. It also marks a milestone toward developing a high-speed, low-cost optical coherence tomography system on a single integrated circuit chip. James [...]

Vanadium Dioxide Micro-Robotics Actuator Fingers

Researchers at Lawrence Berkeley National Laboratory and University of California, Berkeley, have devised a new simple yet powerful microscale actuator that can flex like a tiny finger. Based on a material that abruptly expands and contracts in response to small temperature variations, the actuators are smaller than the width of a human hair and are [...]

Researchers at Purdue have produced a new type of microtweezers able to manipulate objects for building miniature structures, printing coatings to make advanced sensors, and grabbing and positioning live stem cell spheres for research projects. Moreover, these microtweezers could be used to assemble structures in microelectromechanical systems, or MEMS, which include tiny moving parts. MEMS [...]

Microfluidic and nanofluidic lab on chip (LOC) devices are microchip sized systems that can arrange and analyze tiny fluid samples with volumes ranging from a few microliters (a millionth of a liter) to sub-nanoliters (less than a billionth of a liter). They are envisaged to one day revolutionize how laboratory tasks such as diagnosing diseases [...]
