Introduction - Empatica E4 User Manual

INTRODUCTION

The Empatica E4 wristband is a wearable
wireless device designed for comfortable,
continuous, real-time data acquisition in daily
life.
The E4 contains four sensors:
• Photoplethysmography (PPG) to provide
blood volume pulse, from which heart
rate, heart rate variability, and other
cardiovascular features may be derived.
• Electrodermal activity (EDA), used to
measure sympathetic nervous system
arousal and to derive features related to
stress, engagement, and excitement.
•
3-axis accelerometer, to capture motion-
based activity.
• Infrared thermopile, reading skin
temperature.
The E4 operates either in streaming mode
for real-time data viewing on a mobile device
using Bluetooth® low energy or in recording
mode using its internal memory.
Empatica provides software tools that enable
your E4 data to be transferred securely and
easily to other devices:
