Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

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 ...

Engineers unlock the power of exceptional points (EPs) for advanced optical sensing. EPs -- specific conditions in systems where extraordinary optical phenomena can occur -- can be deployed on ...

Using their Mosquito fabrication method, the researchers created a fan-out pattern of multiple thin light paths inside a thin sheet of PDMS. This created four optical channels that could be used for ...

Understanding acoustic feedback in hearing aids. Power consumption challenges in hearing aids. Functionality integration and its impact on energy consumption. The benefits of using photoreflectors for ...

A new publication from Opto-Electronic Sciences; DOI 10.29026/oes.2024.240005, discusses advances in optical micronanofiber enabled tactile sensors and soft actuators. As a perfect combination of ...

For decades, people with diabetes have relied on finger pricks to withdraw blood or adhesive microneedles to measure and manage their glucose levels. In addition to being painful, these methods can ...

A few days ago, we looked into how Apple could one day use brain wave sensors in AirPods to measure sleep quality and even detect seizures. Now, a new paper shows how the company is exploring deeper ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...
