PORTLAND, Ore. — Cheaper and 10 times the power density of lithium-ion batteries — those are the claims MIT researchers are making about their flow battery design. The Massachusetts Institute of Technology said in a press release that the low-cost, simplified flow battery design aims to satisfy the Department of Energy’s target of less than […]

A buck-boost DC/DC converter delivers a regulated output voltage even when the input voltage is below or above that required by the load. Buck-boost converters adequately serve the needs of battery-powered consumer devices where the required input range is rather narrow; in many cases from 1.8 to 5.5 VDC. However, the situation is different when

It may be hard to believe, but that transparent disk in the photo above is actually a fully functioning speaker. A team of researchers at Harvard’s School of Engineering and Applied Sciences have pioneered a never before seen application of ionic conductivity by creating a see-through artificial muscle that can produce sounds spanning the entire
LCD displays are commonly supplied as a module with a built-in driver circuitry usually mounted on a PCB at the rear of the module. While this strengthen the module mechanically, it has some drawbacks such as it increases the thickness of the display module and raises the manufacturing cost. NXP semiconductors describes the Chip-On-Glass technology

Texas Instruments is one of the most dominant technology companies ever. Behind Intel and Samsung, it is the world’s third largest producer of semiconductors. In addition, they are the largest manufacturer of digital signal processors and analog semiconductors. Young students may just know of TI as producers of their world famous graphing calculators. However, for

Professor John A. Rodgers has previously taught us what the future has in store by way of flexible, stampable microelectronics that adhere to the surface of human skin. As revolutionary as those devices can be – providing critical health-related information from real-time physiological monitoring of the human body – they are limited in their ability
