Cat No: BSS-LJX-0009 Datasheet
Product Name: Integrated Biosensor with vAFE and 6-Axis IMU (Inertial Measurement Unit)
Quantities: - +
| Detailed Description | This is a biosensor that integrates a vAFE channel for detecting bioelectrical potential signals and a 6-axis IMU for motion tracking, featuring a high-performance 3-axis digital accelerometer and a 3-axis digital gyroscope. The device incorporates advanced dedicated functions and data processing capabilities for motion handling, such as a finite state machine (FSM), low-power sensor fusion (SFLP), adaptive self-configuration (ASC), and a machine learning kernel (MLC) with derivative AI functions/filters. This product is housed in a small 2.5 x 3.0 x 0.71 mm plastic pad grid array (LGA) package, meeting the demands of ultra-compact solutions. |
| Functions | • Bio-potential Sensing: Using the configurable vAFE channel to read analog signals like ECG or EEG. • Inertial Measurement: Using the 6-axis IMU (accelerometer + gyroscope) to track motion, orientation, and angular velocity. • On-chip Data Fusion & Processing: The embedded Machine Learning Core (MLC) and Low-Power Sensor Fusion (SFLP) algorithm process data from all channels directly on the sensor, enabling features like activity recognition and context-aware analysis without involving the main system processor. |
| Applications | • Advanced Wearable Healthcare: Devices requiring heart rate monitoring with simultaneous activity and gesture recognition. • Motion Analysis with Physiological Context: Applications in sports science, rehabilitation, or ergonomics where understanding both body motion and related bio-signals (like muscle activity) is crucial. • Context-Aware User Interfaces: Systems that respond to both physical gestures and physiological states. |
| Features | • Integrated vAFE + 6-Axis IMU: Combines bio-signal amplification with a full accelerometer and gyroscope. • On-chip Intelligence: Integrates a Machine Learning Core (MLC) for AI-driven pattern recognition, low-power sensor fusion (SFLP) for combining accelerometer and gyroscope data, Finite State Machines (FSM) for programmable motion detection, and Adaptive Self-Configuration (ASC) for dynamic adjustment based on processed outputs. • Synchronized Signal Acquisition: Ensures bio-signals and motion data are perfectly timestamped for accurate combined analysis. • High-Performance Sensing: Features an accelerometer with selectable full-scale ranges of ±2/±4/±8/±16 g and a gyroscope with wide selectable full-scale ranges from ±125 to ±4000 dps. • Configurable vAFE: Supports single-ended or differential input, includes a digital notch filter to reduce 50/60 Hz power line interference. • Flexible Digital Interfaces: Supports SPI, I²C, and MIPI I3C® serial interfaces. • Data Buffering: Large intelligent FIFO (up to 4.5 KB) for efficient data management. • Compact Package: Small form factor (2.5 x 3.0 x 0.71 mm) LGA package. • Wide Voltage Range: Analog supply from 1.71 V to 3.6 V, with flexible I/O supply down to 1.08 V. |
