“A ballistocardiograph chair, designed to look like a normal office chair, was built and fitted with pressure sensitive EMFi-films.”

“This is caused by the compliance between subject and ballistocardiograph as well as by that between the latter and the surroundings.”

“The heart measurement of a chicken embryo takes place by means of a ballistocardiograph as regards technology.”

“Beddit uses ballistocardiography, through an ultra-thin force-sensing strip, to measure nighttime activity without any wearable sensors.”

“Noninvasive methods of heart rate measurement, such as acoustocardiography and ballistocardiography, are also described.”

“In addition, PCA is an easy way to remove the ballistocardiogram artifact by eliminating the first principal component.”

“A motion transducer or more specifically an accelerometer may be used to generate a ballistocardiogram.”

“The authors concluded that sternal acceleration ballistocardiogram combined with hemodynamic and demographic data in a probabilistic model shows promise.”
