Differences between Embrace and E4

Updated:

We make both the E4 and the Embrace, but they serve different purposes. The Embrace is optimized to detect convulsive seizures, and with the Alert App it notifies caregivers to speed up assistance. In some situations, it can also be used for large research studies on a subscription basis. 

Instead, the E4 is a device intended for researchers, so that they can record physiological signals in real-time and do after-the-fact analysis. 

 

USE:

In addition to seizure detection, Embrace can also monitor rest, sleep and physical activity.

The E4 wristband on the other hand, is designed for research on physiology in daily life and is not meant for consumer use. It is flexible with tools for data recording and management as well as real-time streaming to the E4 Realtime App.

E4 data are also accessible in real-time via our mobile APIs for iOS and Android so that you can integrate the E4 wristband into existing protocols with mobile data collection, for sample projects visit https://developer.empatica.com.

 Please bear in mind that the software for each device is unique and designed for different types of users so they are not compatible or interchangeable. Currently E4 software does not work with Embrace and vice versa.
