Biofeedback is a form of self-regulation in which an individual is provided information in the form of sensory feedback about a biological condition or function in order to gain control over that biological function.
To measure changes in EMG with maximal contraction, as compared to baseline, incorporating different combinations of visual and auditory feedback.
To design experiments by selecting different types of muscles and variations of contractions/activities relating to biofeedback that the subject will perform.
Tasks Performed by the Student
May vary, but in example experiment, Subject will:
sit and relax with knees hanging off the edge of a table or seat, with enough room for full knee extension,
look away from the computer monitor and maximally relax (not contract),
look away from the monitor and maximally contract (knee extension) and hold for 2 seconds, and
look at the screen and maximally contract (knee extension) and hold for 2 seconds.
Add event markers throughout the recording.
The software automates the calibration procedure for the student. There are no knobs and dials to confuse the student.
Graph template files ensure consistent setup for subsequent Subjects or repeated trials—plus, you can easily add your own lesson plan to the onscreen journal.
The lesson will also work as part of a group study.

Smart shirt simultaneously acquires ECG and Respiration data while subjects roam freely The lightweight, comfortable BioNomadix BioShirt contains a respiration sensor and fabric electrodes to wirelessly record both respiration and ECG while ambulatory subjects move freely and perform tasks in short or long-term studies, in the lab, or in the real world. The shirt connects to a wireless BioNomadix BN-RSPEC Respiration […]
The Human Anatomy & Physiology Society (HAPS) found that BIOPAC’s Student Lab System (BSL) and AcqKnowledge software were the number one ranked data acquisition and analysis systems for physiology experiments performed in introductory A&P labs. According to HAPS surveys conducted in 2013 and 2016, BIOPAC products are used and preferred by members in more labs than […]
Hardware and software packages from BIOPAC allow commercial consumer marketing teams to easily combine precise eye tracking data with physiological data recording. Here are a few notable studies recording physiology with eye tracking data: Predicting Advertising Success: While neurophysiological methods have become increasingly popular to better understand marketing phenomena among academics and practitioners, the success of […]
