But potential use of smart rings goes further. Because your fingers have easy-to-sense arteries, some of these devices are also able to gather precise data on your body’s vital signals. They do this with sensors such as a 3d accelerometer, gyroscope, heart rate blood oxygen sensor and mor...
* Fingernail polish or fake fingernails may cause inaccurate SpO2 readings.* SpO2 measurements may be adversely affected in the presence of high ambient light. Cover the sensor area from direct sunlight (with a towel, for example) if necessary.* There could be some deviations due to manual ...
The ear as an alternative site for a pulse oximeter finger clip sensor. Finger clip pulse oximetry sensors are commonly used to obtain functional oxygen saturation readings (S(pO2)), but these sensors may perform poorly if the ... JM Haynes - 《Respiratory Care》 被引量: 16发表: 2007年 ...

battery life, along with a slimmer titanium design with recessed sensors and significantly upgraded internals. This includes asymmetric sensor positioning and increased signal pathways. These improvements deliver 120% better SpO2 quality, 30% more accurate blood oxygen readings, and enhanced heart rate ...
