Up until now, the creepy verification tool that requires people to scan their eyeballs to confirm their identity has mostly toiled on the very outer edges of mainstream awareness. But, according to ...

Abstract: In this study, we fabricated a limiting current-type microelectromechanical system (MEMS) sensor and evaluated its sensing performance of oxygen and humidity concentration. The MEMS oxygen ...

With this multipurpose health testing device, you can measure your body temperature and blood oxygen saturation, take an ECG, and listen to your heart and lungs with a pair of headphones.

Abstract: This paper presents a VCO-based EPR-on-a-chip (EPRoC) sensor for portable, battery-operated electron paramagnetic resonance (EPR) spectrometers. The proposed chip contains an array of 14 ...

What if a small sensor could understand space in three dimensions? A maker recently showed how a Time-of-Flight (ToF) sensor can be turned into a basic 3D scanner. The sensor sends out infrared light ...
