New optical sensor using differential guided-mode resonance achieves record sensitivity and portability, enabling real-time ...

This paper presents new approach for unobtrusive indoor fall detection by an IR thermal array sensor. Unlike existing methods that run fall detection at server and require high communication and ...

This Arduino based IR reflectance sensor can be easily modified and adapted for various practical applications, including line-following robots and proximity or edge detection.

There is a strong correlation between physical health and metal ion levels in biological fluids, making them an attractive analyte for noninvasive health monitoring. Given the pressing need for ...
