Optical Health Sensor

Complete Biosensing Solutions for Wearable, Hearable, Portable and In-Ear Applications

Optical health sensor ICs for body-wearable applications track health and wellness with complete biosensing solutions for continuous heart-rate tracking, heart variability, and oxygen saturation. Our portfolio of complete optical sensor solutions includes highly integrated optical modules for space-constrained form factors, high SNR analog front-ends (AFEs) to address low perfusion cases (corner cases), and algorithms that extract meaningful information from photoplethysmography (PPG) signals.

Ultra-low power consumption and leading-edge packaging technology extend product battery life, reduce solution size, and accelerate time-to-market. Our portfolio enables optical sensor solutions for a variety of use cases and body locations.

Our packaging innovation in optical modules has paved the path way for optical biosensing in mobile phones and in-ear headsets. These biosensor optical modules are creatively assembled in optically enhanced packaging. The packaging technology eliminates crosstalk between LEDs and photodiodes (PD) without compromising the optical spacing necessary to extract useful signals from the body.

Our heart-rate (HR) and consumer-grade SpO2 algorithms meet FDA requirements and work seamlessly with our optical sensor devices.
