Laboratorně- demonstrační pacientský simulátor biosignálů

Abstract

This bachelor thesis deals with the design and implementation of an educational biosignal simulator integrated into a teddy bear phantom. The aim was to create a technologically transparent tool intended for the popularization of health sciences and education among the general public. The proposed system consists of a central power supply and four independent, purely analog modules simulating heart rate, body temperature, muscle activity (EMG), and respiratory processes. These circuits provide users with an interactive approach to the physical nature of biosignals without complex digital control. The functionality of the entire solution was successfully verified through subjective evaluation and objective measurements using professional laboratory equipment. The results demonstrated high accuracy, stability, and efficiency of the designed circuits. Comparison with commercial products confirmed that the phantom represents an energy-efficient and affordable alternative with educational potential for long-term autonomous operation.
