If just by looking at our watch or cell phone we can know, in real time, our heart rate, the number of steps we take, the calories we burn and the hours of sleep we got the night before, why can’t we ...

Embedded in cell phones, rings, bracelets or watches, the novel tools aim to make it easier to manage hypertension. But they must still pass several tests before hitting the clinic. By Matías A. Loewy ...

While technologies to measure water vapor loss do exist, they are large, cumbersome machines that largely reside within hospital settings. A new device that measures changes in water vapor, carbon ...

A multi-campus research team has developed a novel device for non-invasively measuring cervical nerve activity in humans. The device has potential applications for supporting more personalized ...

Engineers at Stanford University have created a small, autonomous device with a stretchable and flexible sensor that can be adhered to the skin to measure the changing size of tumors below. The ...

Researchers have created a miniature device for measuring trace levels of toxic lead in sediments at the bottom of harbors, rivers and other waterways within minutes -- far faster than currently ...

Akhil Padmanabha, a PhD student at Carnegie Mellon University's Robotics Institute, has spearheaded the creation of a wearable device designed to measure scratching intensity. This innovative ...

Researchers have developed a device that detects low concentrations of methanol in alcoholic beverages. Swiss experts have created and tested a portable device paired with a smartphone app that can ...

Researchers have designed and reasoned through a tabletop gravity wave detector. Building the real thing will require some new technology to limit factors like decoherence. The principle uses a "large ...

Most of the Hackaday community would never wire a power supply to a circuit without knowing the expected voltage and the required current. But our mechanical design is often more bodged. We meet folks ...
