Evolving Africa's Role in the Advancement of Artificial Intelligence in Photoplethysmography Monitoring
Artificial intelligence (AI)-assisted photoplethysmography (PPG) technology has received considerable attention in recent years due to the rapid expansion of remote healthcare services, particularly during the COVID-19 pandemic. AI-enhanced PPG systems play an important role in improving vital sign assessment, enabling early disease screening, and supporting personalized healthcare. This bibliometric study (2014–2024) investigates global research trends, collaboration patterns, and regional disparities in studies related to AI-driven PPG technologies. The analysis re
