Validity of Micro-Data Loggers to Determine Walking Activity of Turkeys and Effects on Turkey Gait

Frontiers in Veterinary Science, 2019
Accelerometers have the potential to provide objective, non-invasive methods for detecting changes in animal behavior and health. Our objectives were to: (1) determine the effects of micro-acceleration data loggers (accelerometers) and habituation to ...

A review of accelerometer-derived physical activity in the idiopathic inflammatory myopathies

BMC Rheumatology, 2019
Background The idiopathic inflammatory myopathies (IIMs) are a group of rare conditions characterised by muscle inflammation (myositis). Accurate disease activity assessment is vital in both clinical and research settings, however, current available ...

Electrostatic anti-spring-enhanced MEMS accelerometer with auto-tuning capability

Microsystems & Nanoengineering
This study introduces a MEMS accelerometer equipped with an adaptive tuning system for an electrostatic anti-spring. As the input acceleration increases, the sensitivity of the adaptive MEMS accelerometer decreases to compensate for the measurement range.

Quasi-Static Calibration Method of a High-g Accelerometer

Sensors, 2017
To solve the problem of resonance during quasi-static calibration of high-g accelerometers, we deduce the relationship between the minimum excitation pulse width and the resonant frequency of the calibrated accelerometer according to the second-order ...
