Wearable device for emotion monitoring and control for children diagnosed with ADHD (Attention-Deficit/Hyperactivity Disorder) presents a validation study realized by Stressless SRL and Faculty of Psychology, Babes-Bolyai University Cluj-Napoca as part of the collaboration within the program Grant EIT Health InnoStars RIS Innovation (Project  6017/22.04.2020).


The aim of the study was to test and validate an emotional and stress detection technological solution in the form of a wearable device, developed by Stressless SRL.  The Tully device can be seen as an electronic companion, providing an image of children’s daily stress, as well as the ability to assess both the immediate effects of a particular exercise and the long-term evolution of therapy. This will allow children to learn to identify the biological sensations associated with the level of stress and agitation and to control themselves much faster, the device having an immediate effect on children’s behavior. The parameters measured by the bracelet include pulse variability, blood oxygen level, temperature and electrical conductance of the skin (electrodermal activity). It has a built-in accelerometer that detects small and fast movements presented in an episode of hyperactivity, successfully distinguishing them from larger movements (in the context of a sports activity e.g.). TULLY was developed by the lead partner in this research project, SC STRESSLESS SRL, over a 3 years period, between 2017 and 2020. The study was realized over the course of a 6 months period, between July and December 2020. The first data analysis was realized during the first week of December, and the second phase of the study started immediately afterwards, took place for two weeks, until the 20th of December, and generated over 245 hours of data. The results of the study show that firstly that there is a clear difference between the behavioural reaction to stress of children diagnosed with ADHD and those in the typically developing group.
