Clean, safe water is vital for human health and well-being. It also plays a critical role in our food security, supports high ...

If you've ever consumed food made with olive oil, there's a good chance you've unknowingly ingested materials capable of ...

Optical tactile sensors are extensively utilized in intelligent robot manipulation due to their ability to acquire high-resolution tactile information at a lower cost. However, achieving adequate ...

There must be no chemical reaction between the sensor material and the sample. Use a sensor with a low cell constant (0.01 to 0.1 cm-1) for low conductivity measurements and a sensor with a higher ...

Recently, novel fluorescent probes based on biomaterials and luminescent nanomaterials for metal ions attract tremendous attentions, owing to their advantages of simple operation, high sensitivity and ...

High time-resolution monitoring of nitrogen dioxide (NO2) is of great importance for studying the formation mechanism of aerosols and improving air quality. Based on the Griess–Saltzman (GS) reaction, ...

Attendees at this year’s Laser World of Photonics trade show can discover the latest trends in photonics technology, attend ...

Aston University researchers have developed a new class of optical microresonators, miniature optical devices that strongly confine and enhance light in microscopic dimensions. They are essential ...

We analyze the optical wireless sensor network system using corner cube retroreflectors (CCRs). A CCR consists of three concave mirrors. When a light beam enters the CCR, it bounces off each of the ...

Notwithstanding the substantial progress in optical wearable sensing devices, developing wearable optical sensors for simultaneous, real-time, and continuous monitoring of multiple biomarkers is still ...
