BLiv will utilize Transdermal Optical Imaging (TOI) and blockchain tech (tokens, NFTs, Staking etc). Please note that TOI tech is not proprietary and Bliv will use third party providers for this tech. Which is good thing ad Bliv is not dependent on making a breakthrough in TOI and Machine Learning. At the same time, it is easily replicable by others. Overall, it has potential to be successful in combining two different breakthrough technologies and taking it to masses for a good cause.
Transdermal optical imaging (TOI) is a method of detecting blood flow of the face by measuring hemoglobin concentration using a digital video camera. Because of the translucent property of skin, light can travel beneath the skin and re-emit. The re-emitted light from underneath the skin is affected by chromophores, mainly hemoglobin and melanin, which differ in color.
The color difference allows TOI machine learning software to separate the images into layers, which are known as bitplanes. It extracts signals rich in hemoglobin and signals rich in melanin, then discards the melanin-rich signals to obtain a recording of hemoglobin changes under the skin.
TOI has been proposed as an alternative to cuff-based methods of measuring blood pressure because it is able to measure heart rate accurately in a "contactless and non-invasive" way. TOI may also be able to detect hidden emotions using the patterns of blood flow in the face. It can also diagnose diseases that affect blood flow, such as heart disease or stroke.
The accuracy of TOI has been shown to be comparable to traditional methods of measuring blood pressure and heart rate. In a study published in the journal Scientific Reports, researchers found that TOI was able to measure heart rate with an accuracy of 96% and blood pressure with an accuracy of 94%.
