Yobi-PPG™ is a proprietary, second-generation AI-powered optical bio-sensing technology developed by iBaby Labs, a Silicon Valley-based innovator in smart baby monitoring since 2015. It stands for "Yobi Photoplethysmography" (PPG), an advanced form of remote PPG (rPPG), which uses camera-based imaging to detect and analyze subtle physiological signals in humans—specifically infants—without any physical contact, wearables, or sensors
