METHOD AND APPARATUS FOR PHOTOPLETHYSMOGRAPHIC SENSING |
摘要 |
<p>A photoplethysmographic sensing system for determining a user's pulse rate includes a light emitting device (100, 201, 310, 500) including a first plurality of light emitting particles (108, 208, 317) having a first diameter and emitting light having a first wavelength. A detector (118, 218, 500) is positioned to receive light emitted from the plurality of light emitting particles (108, 208, 317) and a processing device (500) determines the pulse rate. The light emitting device (100, 201, 310, 500) and the detector (118, 218, 500) are disposed on a flexible polymeric material (102, 202, 334). The light emitting device (100, 201, 310, 500) may include a second plurality of light emitting particles (108, 208, 317) having a second diameter and emitting light having a second wavelength, wherein the processing device (500) determines the user's blood oxygen level.</p> |
