Researchers at the University of Washington developed a new backscatter sensors that can operate over long ranges with very little power. The researchers demonstrated for the first time that the device runs on almost zero power and can transmit data across distances of up to 2.8 kilometers. Backscatter communication works by emitting a radio signal and […]

The terahertz (THz) region, which is based on 1THz frequency, separates electronics from photonics and has been difficult to access for ages. Semiconductor electronics cannot handle frequencies equal to or greater than 100GHz due to various transport-time related limitations. In other hand, photonics devices fail to work below 10THz as photon’s energy significantly drops to thermal energy. Terahertz […]

The researchers at Stanford University have discovered two ultrathin semiconductors – hafnium diselenide and zirconium diselenide. They share or even exceed some of the very important characteristics of silicon. Silicon has a great property of forming “rust” or silicon dioxide (SiO2) by reacting with oxygen. As the SiO2 acts as an insulator, chip manufacturers implement this property […]

A joint research by the US Air Force Research Laboratory Sensors Directorate and Michigan State University have developed micro-electromechanical systems (MEMS) actuator based on smart materials, specifically vanadium dioxide (VO2). In the room temperature, Vanadium dioxide exhibits the Mott transition. It is a not-well-understood phenomenon known to occur in transition metal chalcogenides and transition metal oxides. The research team […]

Designers can now search SnapEDA’s vast component library directly in PCB123 MULINO, OR and SAN FRANCISCO, CA (September 13, 2017) — Today, Sunstone Circuits, creators of the free PCB design tool, PCB123, and SnapEDA, the Internet’s first parts library for circuit board design, are launching a new integration that allows designers to search for digital […]

I got a couple of Microsemi’s C900502 10.525 GHz X-band Doppler radar motion sensors a while ago. This batch was made in UK and had “UK patents 2243495 and/or 2253108 apply” printed on the case. I have seen a teardown of an HB100 Doppler radar module before and was wondering if I this one is […]

Abstract The use of graphene in electronic devices requires a band gap, which can be achieved by creating nanostructures such as graphene nanoribbons. A wide variety of atomically precise graphene nanoribbons can be prepared through on-surface synthesis, bringing the concept of graphene nanoribbon electronics closer to reality. For future applications it is beneficial to integrate […]

About Chromatron is an open source Wifi pixel controller designed to make LED pixel projects easy and fun. Hi, I’m Jeremy! I’ve designed a toolkit for making art with LED pixel strips, and I’d like to share it with you! Chromatron takes custom designed hardware and feature-packed firmware, sprinkles it with some Python, and serves […]

All electronics projects need power. Power can come from either stored energy in a battery, or directly from mains AC voltage or DC power from renewable sources such as solar energy. Power Management ICs (PMICs) help manage the power requirements in a system including scaling voltages, battery charging, and DC-DC conversion. Choosing the right PMIC […]

Bismuth is considered as a “green-element” and bismuth-based compounds are gaining attention as potentially non-toxic and defect-tolerant solar absorbers. The researchers of the University of Cambridge and the United States developed theoretical and experimental methods to show that bismuth, which sits next to lead (Pb) on the periodic table, can be used to make inexpensive solar cells.
