BIOPAC provides software and hardware that allows research teams to study physiological measures, whether in this reality or in virtual reality, or for a single person or multi-person groups. Here are a few studies focusing on BIOPAC equipment’s ability to record physiological signals, including ECG, EDA, and Respiration.
Pairs Performing Under Pressure
How does acute stress affect real-time cooperation and competitive interaction between people? Pairs of women played a turn-based game while AcqKnowledge Software was acquiring and analyzing the dyad’s ECG signals to see when participants became stressed. Did they cooperate and play better when under acute stress?

A Pair, Inside & Out
People coordinate with one another to achieve joint goals, often spontaneously and without much conscious effort. However, in an interaction, do pairs coordinate their bodily rhythms as well? Using a BioNomadix unit to record Respiration, this study aimed to see whether dyads coordinated bodily rhythms through mutual adaptation (i.e., reciprocity) or by producing more predictable patterns.

Next-Gen Stress Reducer
Reducing stress is a well-proven way to reduce a person’s chance of becoming sick. By creating a relaxing virtual reality environment that people could enter, could they better manage their stress and feel better? A BIOPAC Data Acquisition System was used to record participants’ ECG, EDA, and RESP data while they were in the virtual world.

Many studies use hand dynamometry to objectively quantify exerted effort during experiments most commonly related to the study of motivation.
We’ll focus on this topic and go over everything you need to know to record dynamometry data in the MRI or in the lab. Topics include
– Calibrating for maximum voluntary contraction (MVC)
– Real-time access to the dynamometer signal by third-party applications
– How researchers have used this equipment
– Creating a visual task that gives feedback on exerted effort as well as rewards to the participant
