The ST1VAFE3BX is a versatile biosensor designed for biopotential signal detection and motion tracking. It integrates a vertical analog front-end (vAFE) for capturing biopotential signals like ENG, ECG, and EEG, alongside a high-performance 3-axis digital accelerometer. This combination enables context-aware edge analysis with low power consumption and minimal latency. The device features an embedded machine learning core (MLC) and a finite state machine (FSM) for advanced data processing, adaptive self-configuration (ASC), and event detection, making it ideal for wearable and portable devices, activity tracking, and well-being applications.
