GENERAL DESCRIPTION

The vital sign monitoring (VSM) watch, EVAL-HCRWATCH4Z, is

a modular development, demonstration, and data collection

platform for high performance vital signs monitoring

applications based on Analog Devices, Inc., analog front ends

and sensors.

It is a wearable, battery-powered device which enables the

continuous monitoring and on-demand spot check

measurement of photoplethysmography (PPG), electrodermal

activity (EDA, bioimpedance-based), skin temperature,

electrocardiography (ECG, biopotential based), and

motion/activity (based on a 3-axis accelerometer).

It allows for synchronized, multiparameter data storage on

internal memory for later data retrieval and offline analysis

and/or live monitoring on a PC (Windows® OS) or Android

or iOS-based device.

PREPARING THE VSM WATCH

Before using the VSM watch, proper preparations must be

made. Ensure the battery of the watch is charged and the

WaveTool program for PC is successfully installed. See the

Powering Up the System for the First Time sections for

installation instructions. The watch firmware must be

upgraded using the VSM WaveTool.

ADI Confidential VITAL SIGNS MONITORED To minimize the power line interference (50 Hz/60 Hz) and improve the quality of the output signal, it is recommended to use the BLE link. PHOTOPLETHYSMOGRAPHY (PPG)— ADPD4100 ELECTROCARDIOGRAPHY - AD8233 The AD8233 is a 50 µA 2.0 mm × 1.7 mm WLCSP low noise single lead analog output biopotential front end.

Electrical Specifications of the AD5940 SKIN AND AMBIENT TEMPERATURE The skin temperature measurement is based on a thermistor (NTCG104EF104FTDSX). The thermistor used in the skin temperature measurement is thermally coupled to the bottom of the watch.
