Researchers have designed a low-cost, stable and ultrafast responsive sensor that is easy to manufacture, overcoming the challenge of producing a simple, fast and highly sensitive version. A*STAR ...

A research team develops a real-time humidity sensing optical sensor. The response time of the new sensor is 10,000 times faster than the conventional sensors and can be mass-produced at low cost. The ...

There is a point where taking technology for granted hides some of the incredible capabilities of seemingly simple devices. Optical mice are a great example of this principle, using what are more or ...

The circuit shown in the figure measures relative humidity in air at the low temperatures found in applications like cold storage of food items and greenhouses. Instead of using electrical signal ...

The Apple iPhone brought the benefits of integrated multi-sensor technology to the masses, and while the application of sensors and their associated algorithms has multiplied and changed the world ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

The Hong Kong Polytechnic University (PolyU) has developed new side-hole polymer optical fiber sensors, which can be used in multiple medical treatments without the drawbacks of other optical fibers ...

(Nanowerk News) The Hercules beetle native to South America has a fascinating trait of changing its shell colors depending on the external humidity conditions. This is because the inside of the beetle ...
