Development of an Inertial Measurement Unit (IMU) with datalogger and geopositioning for mapping the Earth's magnetic field. [PDF]

HardwareX, 2023
The Earth's magnetic field is used in various navigation systems, but this field has a dynamic behavior that can be affected by different physical factors in local environments. These factors can pose risks to navigation systems and at the same time be a signal of a phenomenon that needs to be investigated, such as mineral concentration or the presence

Assessment of Breathing Parameters Using an Inertial Measurement Unit (IMU)-Based System. [PDF]

Sensors (Basel), 2018
Breathing frequency (fB) is an important vital sign that—if appropriately monitored—may help to predict clinical adverse events. Inertial sensors open the door to the development of low-cost, wearable, and easy-to-use breathing-monitoring systems. The present paper proposes a new posture-independent processing algorithm for breath-by-breath extraction ...

Reliability of a Low-Cost Inertial Measurement Unit (IMU) to Measure Punch and Kick Velocity. [PDF]

Sensors (Basel)
Striking velocity is a key performance indicator in striking-based combat sports, such as boxing, Karate, and Taekwondo. This study aims to develop a low-cost, accelerometer-based system to measure kick and punch velocities in combat athletes. Utilizing a low-cost mobile phone in conjunction with the PhyPhox app, acceleration data was collected and ...

Enhanced 6D measurement by integrating an Inertial Measurement Unit (IMU) with a 6D sensor unit of a laser tracker [PDF]

Optics and Lasers in Engineering, 2020
Abstract Six-degree-of-freedom (6D) sensors enhance the measurement capability of traditional three-degree-of-freedom (3D) laser trackers. However, the classical 6D measurement techniques still have shortcomings in actual use, such as the problem of line of sight and relatively low data acquisition rate.
