Embrace2 is an FDA-cleared wrist-worn medical device that records physiological signals. Data recorded by Embrace can be accessed and downloaded from the Empatica Research Portal for offline analysis.
Embrace2’s sensors measure physiological parameters which are used for seizure, sleep, and activity analysis. The sensors monitor:
- Electrodermal Activity (EDA, also known as skin conductance): measures variations of the electrical conductance of the skin. EDA is a measure of autonomic nervous system (ANS) arousal and reflects strong emotional states such as fear, anxiety, anger, and positive excitement. The EDA sensor sampling rate is 4Hz.
- Motion: measured by a 3-axis accelerometer sampled at 32Hz.
- Skin surface temperature: measured by a Peripheral Temperature Sensor sampled at 1Hz.
On top of raw sensor data, we also monitor rest, physical activity, autonomic nervous system arousal, and generalized tonic-clonic seizures (GTCS). Our team of data scientists is constantly working on refining and developing algorithms. Contact us at email@example.com for more information.
- Embrace2’s battery life lasts 48+ hours after a full charge.
- The charging time is about 1 hour 40 minutes.
- Embrace can store up to 14 hours of data on its internal memory. If Embrace memory fills up, it will stop recording. Physiological signals that were collected will not be overwritten with new data.
- The internal clock of the Embrace watch syncs with the time on a paired device.
- Embrace is water-resistant for up to 1 meter/3 feet. It can be worn in the shower or swimming pool, so long as it does not come in contact with salt water.
