In this design solution, we consider some of the challenges and constraints when developing a custom photoplethysmography (PPG) solution using an optical sensor IC in hearable or in-ear fitness and health wearable devices such as earbuds.
The MAXM86161 in-ear heart-rate monitor and pulse oximeter is the market’s smallest fully integrated solution that delivers highly accurate heart-rate and SpO2 measurements from hearables and other wearable applications. MAXM86161 delivers approximately 35 percent lower power to extend battery life of wearables.
