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 ...

The reliable, noninvasive measurement of dissolved gases in microfluidic devices is an important and difficult activity for biological applications. The PreSens pCO 2 mini and chemical optical CO 2 ...

Physicists Shubhayan Sarkar, Armin Tavakoli Orthey Jr., and Remigiusz Augusiak have published a scheme in Nature Physics that ...

Primary performance data for passive fiber-optic devices is provided by spectral measurement of optical insertion loss (IL) and polarization-dependent loss (PDL). Often used to characterize optical ...

Choosing the operating system (OS) on which to build the application is the first step to building a PDA-based measurement device. Engineers almost always select between Palm OS or Pocket PC since ...

A laser Doppler vibrometer’s (LDV) real-time capability enables measurement times roughly six orders of magnitude smaller compared to any method that is based on strobe techniques or provides a ...

Although many people routinely pinch their belly in order to see how fat they're getting, that's really only a measure of their subcutaneous "under the skin" fat. The Bello device goes deeper, using ...

As the Internet of Things in all its manifestations continues to roll out, developers will need a variety of test strategies to ensure low power consumption, suitable RF performance, and even audio ...
