BIOPAC provides software and hardware that allows research teams to record and analyze numerous body signals for physiological experimentation. Here are a few notable studies using BIOPAC equipment for ECG, EDA, and Respiration data.

What Keeps Students More Engaged?

The question has been brought to the forefront during COVID, what variations of online learning keep students more engaged? Is it videos featuring lecturers or videos featuring infographics? By measuring EDA with a BIOPAC MP system and wireless EDA amplifier, this study was able to see which method of video kept students’ attention longer.

Could ECG Data Lead to Safer Roads?

Could combining physiological data of drivers with safety features of vehicles make roads safer? Could vehicles respond to ECG data in real time? Using a BIOPAC MP data acquisition unit and AcqKnowledge software, this study was able to improve ECG data collection from drivers who became stressed while driving in simulated conditions.

Can Muscles Catch Their Breath?

After exercising, most people breathe heavily to increase oxygen going into their body to recover faster. Do our muscles mimic us as they recover too? With a BIOPAC data acquisition unit, researchers were able to measure heart rate, body temperature, and arterial pressure of rats. The rats’ muscles were electrically stimulated to see if oxygenation levels changed while muscles contracted and physiological measures increased.
