Accelerometer-based atrioventricular synchronous pacing with a ventricular leadless pacemaker: Results from the Micra atrioventricular feasibility studies.

Heart Rhythm, 2018
BACKGROUND Micra is a leadless pacemaker that is implanted in the right ventricle and provides rate response via a 3-axis accelerometer (ACC). Custom software was developed to detect atrial contraction using the ACC enabling atrioventricular (AV ...

The role of accelerometer-derived sleep traits on glycated haemoglobin and glucose levels: a Mendelian randomization study

Scientific Reports
Self-reported shorter/longer sleep duration, insomnia, and evening preference are associated with hyperglycaemia in observational analyses, with similar observations in small studies using accelerometer-derived sleep traits.

Review: Fifty Years Plus of Accelerometer History for Shock and Vibration (1940–1996)

Shock and Vibration, 1999
This article summarizes the history of accelerometer development and the subsequent evolution of the commercial accelerometer industry. The focus is primarily on piezoelectric and piezoresistive accelerometers, although early resistance-bridge-type ...

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 ...

Reliable recognition of lying, sitting, and standing with a hip‐worn accelerometer

Scandinavian Journal of Medicine & Science in Sports, 2018
Hip‐worn accelerometers are widely used to estimate physical activity (PA), but the accuracy of acceleration threshold‐based analysis is compromised when it comes to identifying stationary and sedentary behaviors, let alone classifying body postures into

Categorising sheep activity using a tri-axial accelerometer

Computers and Electronics in Agriculture, 2018
An animal’s behaviour can be a useful indicator of their physiological and physical state. As resting, eating, walking and ruminating are the predominant daily activities of ruminant animals, monitoring these behaviours could provide valuable information
