Research activity monitor eTact

wearablewatch-type

Actimetry allows the fine analysis of physical activity to better understand the segmentation of the sleep/wake rhythm and the sleep quality of the subject in the context of sleep disorders, to control the implementation of an adapted physical activity program, to monitor subjects suffering from chronic disease, etc. Integrating a 3D accelerometer, the eTact patch collects the subject’s activities and gives access to a skin temperature indicator. The solution collects actimetric data using the TAT (Time Above Threshold) method. This method is the most commonly used in actimetry; it is based on the sum of the predefined acceleration threshold overruns over a given period. Once the data download from the patch, each value will allow the creation of an histogram / actogram. The eTact® electronic device is rechargeable and reusable. The eTact solution is composed of: A patch; A PC/MAC software eTact Watcher dedicated to the eTact patch configuration and data downloading; A dedicated USB cable allowing data transfer and power supply; A data analysis tool eTact Analysis allowing to estimate daytime activities and sleep quality of the subject through indicators calculation. Depending on the use, the patch should be worn on the non-dominant wrist using a dedicated bracelet or fixed using a suitable bandage to any other part of the body. The data collected are directly stored in the internal memory of the patch. The battery autonomy of the patch is around 5-6 days, depending on the configuration used, but it can be recharged successively without the need to download the data stored.
