Background: Recent advances in the field of wearable technology are now at a peak in the sports field and the medical field. The validity, reliability, and application of such systems are still under research and yet to be revealed.
Purpose: This study aims to design and constructing the Inertial Measurement Unit (IMU) hardware with the required software to collect accelerometer data for potential use in human movement studies and test the efficacy of the collected IMU accelerometer data by comparing it with the motion capture data.
Methods: In this study, the IMU sensor is coupled with the Arduino, loaded with …

A four-phase, chronological, and build-up approach was implemented that commenced with basic hardware testing in a centrifuge and culminated in flights augmented by real-time biofeedback displays. A prototype Portable Electrocardiogram Unit (PECGU) was designed and proven to accurately measure heart rate (HR) and display percent heart rate reserve (%HRR). Results showed that %HRR was not a sole predictor of cognitive state. Cognitive responses indicated some correlation with %HRR, but were influenced by environment (centrifuge vs. flight). Subjective perceived exertion levels did not show statistically significant changes during test with biofeedback. A G-tracking task was evaluated during centrifuge and flight tests. …
