Its calibration-free operation, in contrast to other systems that require cuff measurements, is a noteworthy advantage. Director of the Digital Health Lab Edward Wang emphasizes that the clip offers reliable readings without the need for extra apparatus.
This feature makes measurement easier, improving accessibility and convenience. The tech has a big potential because it provides a cheap and simple way to treat illnesses like hypertension.The user applies pressure with a fingertip while following instructions from the unique smartphone app to measure blood pressure using the clip. The clip, a plastic attachment that wasIts optical structure is similar to a pinhole camera.
The diameter and brightness of the circle reveal details about the pressure being applied and, separately, the amount of blood in the fingertip. Following the algorithmic processing of these measures, systolic and diastolic blood pressure readings are obtained.participated in validation tests to show that the clip's outcomes were comparable to those obtained using a blood pressure cuff.
The researchers believe that the current design of the clip should work with different phone types even though it has only been tested on one specific smartphone model. The team's future goals include improving the technology's usability for older persons in particular and validating its accuracy for a range of skin tones. They also aim to create a more ubiquitous design.
