Paving the way for predictive healthcare of the human body
Your gateway to smarter, more responsive, and energy-efficient wearables
Your gateway to smarter, more responsive, and energy-efficient wearables
ST unveils the ST1VAFE3BX, the first dual-function biosensor combining a vertical analog front-end (vAFE) for detecting biopotential signals and a 3-axis ultralow-power accelerometer for motion tracking. Biopotential and motion signals are fully synchronized, enabling unique in-the-edge context aware analysis and enhancing reliability of the reading by compensating for motion artifacts. Housed in a compact 2 x 2 mm package, the ST1VAFE3BX is ideal for wearables designed to unlock predictive healthcare by monitoring movement and body biosignals for diverse applications. Enjoy ultra-low power consumption, low latency, and unique context-aware edge analysis.
