Right now, Rogers and his students are evaluating stretchable sensors that measure body temperature, monitor exposure to ultraviolet light, and check pulse and blood-oxygen levels. They’re also developing sensors that can track changes in blood pressure, analyze sweat, and obtain signals from the brain or heart for use in electroencephalograms and electrocardiograms...
EasyEDA: A free cloud-based tool for schematic capture, PCB layout, and circuit simulation
06.30.2016 · Articles
A few weeks ago, I had an opportunity to try a new electronics design automation tool called EasyEDA. It is a free web-based tool for schematic capture, PCB layout, and circuit simulation. The best part of any cloud- or web-based development tool is that it runs on a remote server (no worries to install on local machines), always up to date, and is accessible from anywhere through internet...

I turn the key to start the little Ford SUV I’ve rented for my visit to the University of Illinois at Urbana-Champaign, and a message flashes briefly on the dash: “Tire pressure low.” I ignore it. My own car is 12 years old; I’m not accustomed to a car that monitors its own health. Turns out, though, that the little Ford wasn’t kidding. The next morning I find the car has a flat tire...
