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, ...

Light triggers atomic shifts in asymmetric 2D semiconductors, tuning their optical response. This enables compact, ...

Analog and digital optoelectronic sensors combine an LED and an optoelectronic integrated circuit in a compact package to enable optical encoders to provide absolute or incremental position detection ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

Researchers have developed a tiny fiber optic force sensor that can measure extremely slight forces exerted by small objects. The new light-based sensor overcomes the limitations of force sensors ...

Researchers are making key advances with a new type of optical sensor that more closely mimics the human eye's ability to perceive changes in its visual field. Researchers at Oregon State University ...

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...

Traumatic brain injury is a major cause of death and disability. When a patient attends an A&E or neurocritical care unit with a head injury, one of the most important parameters to assess injury ...

Sometimes we need a non-contact liquid level sensor. There are several ways to build that, but the easiest is to try an optical liquid level sensor. You may already have an idea in mind since you are ...

Smartphone cameras have improved dramatically since the first camera-equipped cell phone was introduced in 1999, but they are still subject to tiny errors in the alignment of different wavelengths of ...
