In this article, we discuss the problem that racial bias in pulse oximetry poses, the pressure on the FDA to address that bias, and the prospects for its near-term resolution. Although the impact ...

Nanoscale luminescent force sensors excel at measuring piconewton forces, while larger sensors have proven powerful in probing micronewton forces. However, large gaps remain in the force ...

Two studies show that the light emitted by nanocrystals embedded with luminescent ions can be used to sense forces with high spatial resolution — even when those forces are inside a microscopic ...

The heart rate sensor has an accuracy of 1 beat per minute (BPM), while the SpO2 sensor has an accuracy of 1%. The accelerometer’s maximum full scale is ±16g, and the pressure sensor boasts a high ...

【Pulse Oximeter】A pulse oximeter measures the saturation of blood oxygen in the bloodstream. 【Health Monitoring Indicator】Oxygen saturation can reflect early medical problems such as the ...
