Failures can occur in the electrical disconnect switches, fuses or circuit breakers that control, protect and isolate electrical equipment in electrical power systems, also known as switchgear. When a ...

Shan Dou (from left), Jonathan Ajo-Franklin, and Nate Lindsey were on a Berkeley Lab team that, in collaboration with researchers from Stanford, used fiber optic cables for detecting earthquakes and ...

A novel dual-core optical fiber made from stretchable materials offers a flexible approach to optomechanical sensing, researchers report. It can distinguish and measure complex mechanical movement ...

A new fiber-optic sensor made from stretchy rubber rather than glass can be integrated into wearable electronics and measure movement. The sensors can also quantify the force of stretching, bending, ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. The technology could enable household testing for ...

Cornell researchers have created a fiber-optic sensor utilizing inexpensive LEDs and dyes that resulted in a stretchable skin-like material able to detect deformations, including pressure, bending, ...

Designers of composites are learning that if they are to be able to guarantee component and system performance, repeatability and reliability, it is critical that they have access to more sensor and ...

Earthquake detection technologies are usually notably expensive and require the use of seismometers, which are expensive to install as well as maintain. However ...
