Distributed fiber-optic sensors are widely used to monitor temperature and strain in infrastructure, but their spatial resolution has long been limited. In a new study, researchers from Shibaura ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

After more than two decades of intense research and development, distributed optical fiber sensing has become a mature technology, showing clear advantages over its traditional counterpart based on ...

Electrical signals control a vast number of activities in the human body, from exchanges of messages between brain neurons and stimulation of the heart muscle to the impulses that enable hands and ...

Sensing part presence in machines, in fixtures, and on conveyors is an important component of industrial automation. Error-proofing assembly and controlling sequence based on presence or absence of a ...

Assessing spinal curvature is one of the key aspects of diagnosing back pain and related disabilities, and deformation of the vertebral column (VC) can cause anything from minor pain to immobility.

The trick to creating a better quantum sensor? Just give it a little squeeze. For the first time ever, scientists have used a technique called “quantum squeezing” to improve the gas sensing ...

In the past, the progress of cure for thermosetting polymers has been estimated from the measurement of a single, easily monitored parameter, such as resin temperature. As discussed in Chapter 3, such ...

Frequency modulation spectroscopy is a nondestructive technology for determining the water activity of pharmaceutical samples. This article discusses the various pharmaceutical applications of ...
