Market Overview
Photoplethysmography (PPG) sensors have emerged as a foundational technology in the wearable health monitoring landscape. By emitting light typically green, red, or infrared into the skin and measuring the reflected signal from blood flow dynamics, PPG sensors provide valuable data on cardiovascular metrics. The non-invasive and cost-effective nature of PPG has led to its adoption in a broad range of consumer, clinical, and fitness applications. Initially limited to basic heart rate monitoring in wearables, PPG technology has evolved to support continuous blood oxygen tracking, respiration rate estimation, vascular aging assessment, and even stress and sleep monitoring. When combined with advanced digital signal processing (DSP) and machine learning models, PPG sensors offer near-clinical accuracy in ambulatory environments.Consumer electronics giants such as Apple, Samsung, Huawei, and Garmin have standardized PPG-based biosensing in their smartwatches and fitness bands. Meanwhile, the clinical domain is increasingly adopting FDA-cleared PPG-based devices for chronic disease management, postoperative care, and elder health monitoring.
