To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists have created a new type of light sensor that is both flexible and highly sensitive.

Smart home automation is the ultimate life hack, in my humble opinion. Whether for efficiency, accessibility, nerding out, or just plain laziness, all you need are smart home devices and a little ...

Discover a sensor the size of an IC that works by measuring the time it takes light emitted to bounce off of a target and return. About a year ago, a coworker told me about a new kind of distance ...

Ambient light sensors (ALSs) are photodetectors that approximate the human eye’s response to light intensity under a variety of lighting conditions and through different attenuation materials. They’re ...

A wearable fitness tracker makes use of special gizmos to keep track of various parameters of the individual wearing the tracker. These sensors measure a number of parameters such as acceleration, ...

Scientists have discovered the function of a third type of light sensor in the eye -- not vision, but control of the body’s internal clock -- opening a new pathway for potential treatments of ...

Optical sensors may be uniquely suited for use in robotic hands, according to researchers who have developed a three-fingered soft robotic hand with multiple embedded fiber optic sensors. They also ...

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 ...

What are the most common types of light sensors? Two of the most common light sensors are phototransistors and positive-intrinsic-negative (pin) photodiodes. Both generate signals that vary with ...

To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists from Nanyang Technological University, Singapore (NTU Singapore) have created a new ...
