Problem
Wearable devices often struggle to accurately measure biometric data like heart rate and blood oxygen levels due to limitations in sensor size, power consumption, and interference from ambient light. Existing photoplethysmography (PPG) sensors can be bulky, power-hungry, and susceptible to noise, hindering their integration into compact devices like earbuds and impacting the reliability of health monitoring.
Solution
Senbiosys has developed a compact, high-fidelity PPG sensor integrated into a custom IC designed for seamless integration into health-aware earbuds and other wearable devices. The sensor leverages advanced CMOS image sensor technology and a monolithic design to achieve precise biometric measurements while minimizing size and power consumption. Integrated ambient light cancellation ensures robust operation and accurate data capture under various environmental conditions. This technology enables continuous and reliable health monitoring in wearable form factors.
Target Audience
The primary target audience includes manufacturers of wearable devices, particularly those producing health-aware earbuds, fitness trackers, and other compact health monitoring devices.
