Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Recently I came across some non-contact liquid level sensors and gathered them out of curiosity. They have been available in the market for the past few years, but this time I was lucky enough to get ...

Electronic devices and sensors that exhibit large amounts of mechanical deformability have many applications in smart wallpapers 1,2, physiological body sensors 3,4,5,6,7, and human-machine interfaces ...

The CAP-100 Series capacitive liquid-level sensors provide accurate level sensing through the walls of plastic, glass, and fiberglass bottles. The sensors are suitable for medical applications such as ...

Thanks to billions of years of evolution, cells are remarkably adept at detecting pathogens or toxic chemicals in the environment. Taking advantage of this natural surveillance capability, researchers ...

Scientists at the University of Sussex have created a sensor that could someday keep babies from dying of sudden infant death syndrome (SIDS). It takes the form of a flexible rubber tube filled with a ...

Currently, if you want to check water supplies for the presence of toxic bacteria, you have to take a water sample and then culture it in a lab over several days. In the meantime, it's impossible to ...
