Wearable technology for personalized identification and management of paroxysmal atrial fibrillation triggers – TriggersAF

Atrial fibrillation (AF) is the most common arrhythmia diagnosed in 33 million people worldwide. AF is a progressive disease that initially manifests as spontaneously intermittent paroxysmal episodes (PAFs). The project will develop a paroxysmal atrial fibrillation arrhythmia management system consisting of a wrist-worn device, server data analysis software, and a program for a smart device.

Objective Assessment of Physiological Response to Pain Using Machine Learning Technologies (pAInLESS)

In the project, A. Rapalis, in collaboration with other KTU and LSMU researchers, developed a prototype of the diagnostic system based on machine learning algorithms to assess the experience of the pain of different intensities using dynamic multimodal physiological signals and biochemical markers. The expected results of the project would not only take a step towards the development of objective methods for assessing the level of pain, but also simplify pain assessment and facilitate the work of medical staff in the application of individualized analgesia.

Personalized wearable technologies for evaluating life threatening health conditions in chronic kidney disease patients – KidneyLife

The KidneyLife project aims to create and explore non-invasive, unobtrusive technology for detection of life-threatening conditions by using multimodal biosignals: bio-optic, bio-electric, and biomechanical. The comfort of the wearer will be ensured by integrating biosignal sensors and developed algorithms into a wrist-worn device.
