Compact biosensor combines vAFE and accelerometer

The ST1VAFE3BX is the first compact, dual-function biosensor combining a vertical analogue front-end (vAFE) for detecting biopotential signals with a 3-axis low-power accelerometer for consumer and medical motion tracking and wearable applications.

This compact, low-noise, and low-power biosensor with configurable input impedance is ideal for wearables and predictive healthcare.

It delivers low latency and unique context-aware edge analysis with an embedded Edge AI machine learning core housed in a compact 2 x 2 mm package.

With synchronized biopotential and motion signals, the sensor also delivers enhanced compensation for motion artefacts.

Mouser also stocks the STMicroelectronics STEVAL-MKI250KA biosensor evaluation kit. The kit consists of a PCB with a pre-mounted ST1VAFE3BX biosensor and a high-performance 32-bit microcontroller (MCU) that functions as a bridge between the sensor and a PC.

This MCU enables the use of the downloadable graphical user interface (MEMS Studio) or dedicated software routines for customized applications.

The kit makes the complete ST1VAFE3BX pinout available and is recommended for use with the STMicroelectronics STEVAL-MKI109V3 motherboard or STEVAL-MKBOXPRO IoT programmable wireless box kit.
