In recent years, there has been a growing trend in wearable technology: trackers that look like a fashion accessory and yet are smart enough to help us understand our bodies better. If you’ve ever ...

Researchers have developed a laser-based device that can measure blood flow noninvasively and differentiate stroke risk based on current physiological conditions. When physicians want to know more ...

Researchers have discovered a novel, non-invasive way to measure blood flow to the brains of newborn children at the bedside -- a method that has the potential to enhance diagnosis and treatment ...

Researchers at Brown University have developed a wearable sensor that uses polarized light to improve the accuracy of ...

To image microscopic vessels and measure blood flow in the brain, researchers use a tool called ultrasound localization microscopy. It works by using microscopic bubbles circulated through the ...

Apple has your health in mind when it comes to the Apple Watch, which is why it added a blood oxygen sensor starting with the Series 6. This technology can tell if you’re getting enough oxygen to your ...

Using optical techniques to assess blood sugar levels is a promising route to monitoring diabetes in patients, potentially allowing alternatives to invasive blood sampling techniques. Recent examples ...

Caltech and the Keck School of Medicine of USC have developed a new laser-based headset device that can noninvasively measure blood flow and volume. Caltech postdoctoral scholar Simon Mahler is shown ...
