The Empatica E4 wristband is a wearable research device that offers real-time physiological data acquisition. This device is equipped with:
- PPG sensor: measures heart rate variability through blood volume pulse
- EDA sensor: measures electrodermal activity and electrical proporties on human skin
- 3-axis accelerometer: measures acceleration & movement
- Infrared thermopile: measures skin temperature
The included Empatica software helps to import, export and visualise collected data. In our lab, the Empatica is used to measure the level of arousal within individuals in a laboratory and/or naturalistic setting, for example, to study stress and emotions.
How to use Empatica E4?
A user manual is available here. Please be aware that Empatica will discontinue all Empatica E4 products at the end of August 202, including software products such as E4 connect, E4 manager, E4 realtime app, E4 streaming server, and E4 SDK.
The Empatica EmbracePlus is the latest wearable research device of Empatica that offers real-time phsyiological data acquisition. Similar to the Empatica E4, it is also equipped with:
a custom PPG sensor,
an EDA sensor,
an accelerometer, and
a peripheral thermometer.
However, in contrast to the E4, the EmbacePlus provides a wide range of digital biomarkers. These biomarkers are data that are pre-processed by Empatica’s proprietary algorithms. Examples of the digital biomarkers include, but are not limited to:
pulse rate variability,
skin conductance level,
step counts, and
metabolic equivalent of tasks.
Furthermore, the Empatica EmbracePlus comes with a complete updated software suite, including a mobile app to transfer all data to Empatica Cloud (i.e., Empatica Care Lab) and a dedicated online portal to manage participants and access the raw data and digital biomarkers (i.e., Empatica Health Monitoring Platform). The Empatica Health Monitoring Platform provides multiple tools, libraries, and software that can be used to access and read the files generated by the platform.
