By placing the sensor close to the skin and letting it move and flex with the skin, the impact of motion artifacts as well as the noise from ambient light could be reduced [42]. The MAX30100, integrated heart rate monitor sensor and pulse oximetry [43], is used in this study. This ...
This design patch operates on a 3.3-V and uses a 2-layer flex PCB to reduce thermal mass and maximize board flexibility. The primary benefit of flexibility is the ease and comfort for the wearers, which improves the likelihood that the patch remains static on the patient. U1 is the TMP...
