STMicroelectronics has announced the ST1VAFE3BX bio-sensor chip for next-gen healthcare wearables.
The chip combines biopotential input with inertial sensing and AI to facilitate heart rate variability, cognitive function and mental state capabilities.
ST customers BM innovation GmbH and Pison have adopted the chip to drive new-product development.
BMI used the chip to develop a precise athlete performance monitoring system with ECG analysis in a chest band or a small patch.
Pison added the chip to enhance the functionality and user experience of its wearable devices.
The ST1VAFE3BX chip is in production in a 2mm x 2mm 12-lead LGA package and available from ST's store and distributors.
Visitors to Electronica 2024 will see the ST1VAFE3BX in a sensory technology demonstration at the ST booth from 12 to 15 November.
The chip lifts the game in wearables, delivering motion and body-signal sensing in an ultra-compact form factor with frugal power budget.
The ST1VAFE3BX's bio-detection signal channel integrates an accelerometer for inertial sensing and machine-learning core (MLC) with finite state machine (FSM).
The ST1VAFE3BX can provide functionality such as activity detection autonomously, to accelerate system responses and minimise power consumption.
