Self-powered sensor automatically harvests magnetic energy

MIT researchers developed a battery-free sensor that harvests energy from its environment, designed for long-term data monitoring in inaccessible locations like ship engines. The sensor captures energy from magnetic fields around electric wires, operating without battery replacement or complex wiring. This innovation is beneficial in applications with limited power access. The team overcame challenges, such as enabling the sensor to start without initial power " cold start " and efficient energy storage using capacitors. The microcontroller manages stored energy, simplifying installation and expanding deployment potential in various environments, offering more efficient and sustainable monitoring solutions in industrial settings.

Analog Life - Remembering Jim Williams

Being an analog circuits fanboy and have read some of Jim's design sheets from Linear Technology, while digging through the internet, I found this old post by CHM. It's funny to know that "Jim's work bench, which was previously on display at the Computer History Museum, has been on display at Linear for the past few years, but the new building (reportedly) doesn't has space for it." https://computerhistory.org/blog/an-analog-life-remembering-jim-williams/...

SCAMP Vision Sensor, a full-stack project from silicon device to analysis software

https://personalpages.manchester.ac.uk/staff/p.dudek/scamp/default.htm#Architecture I attended this workshop yesterday by Prof. Dudek at IISc, Bengaluru. SCAMP is an extensive project well documented with tool support. This basically is a supercool vision sensor(camera) optimized and light weight suitable for robotics, VR, automotive, surveillance applications. The specialty is that everything is customized from the silicon level which makes the camera process at insane FPS. Open sourced at https://scamp.gitlab.io/scamp5d_doc/...

Researchers Claim First Functioning Graphene-Based Chip

Researchers at Georgia Tech, led by Professor Walt de Heer, have developed the world's first functioning graphene-based semiconductor, potentially revolutionizing electronics with faster traditional computers and new possibilities for quantum computing. Published in Nature, their research utilizes epitaxial graphene, a carbon crystal bonded to silicon carbide, to create a novel semiconducting material, semiconducting epitaxial graphene (SEC), also known as epigraphene. This material exhibits enhanced electron mobility compared to silicon, enabling transistors to operate at terahertz frequencies, about 10 times faster than current silicon-based transistors. This new semiconductor exhibits a significant bandgap, a key requirement for efficient transistors, and could mark a paradigm shift in electronics, moving beyond silicon to more efficient and compatible materials like silicon carbide and boron nitride. While promising, the technology still requires further development to fully realize its potential in digital electronics and quantum computing....
