SignAPROS: An integrated hardware and software system for acquisition, processing, and analysis of bio-signals

SignAPROS is a cost-effective hardware–software system for signal acquisition, featuring modules for database management, protocol configuration, and machine learning-based analysis. It supports up to four Electromyography bi-polar channels and various sensors to measure heart rate, temperature, inclination, and galvanic skin response. The system has already been used in the implementation of a protocol aimed at capturing electrical signals from facial and neck muscles to detect mispronunciation in a second language supporting a master’s project. With a user-friendly interface, SignAPROS enables users to conduct bio-signal acquisition, analyze data, and visualize results efficiently, making it a versatile and accessible tool for scientific studies. • Software and hardware system for bio-signal acquisition with multiple devices. • A system that enables multi-purpose protocols for acquiring bio-signal. • Data characterization based on windowing and statistic measures. • Data analysis by defining and implementing machine learning algorithms. • Customizable for acquiring, pre-processing, visualizing and analyzing signals.
