Texas Instruments Multiparameter BioSignal Monitor Design Guide
This document provides design resources and specifications for Texas Instruments' Multiparameter Biosignal Monitor (MPBSM), a wearable device capable of measuring ECG, GSR, temperature, and motion. It includes hardware schematics, software algorithms, and NFC communication for Android integration. The system uses flexible substrates and gold-plated probes for skin adhesion and durability. The guide is intended for developers to evaluate and customize the system for medical, fitness, and wearable applications.
The MPBSM is powered by ultra-low-power components and can operate continuously on battery. It uses a combination of sensors and algorithms to derive multiple health metrics, including heart rate, respiration, cadence, and dehydration indicators, displayed via an Android app using NFC. This manual is written in Chinese.
