Abstract: The invention generally pertains to reducing artifact noise signals present when non-invasive capacitive-type signal measurements are taken of static electric fields produced by an object of interest. According to a first preferred embodiment of the invention, a given static artifact signal is reduced by minimizing the potential difference between a ground point of sensor circuitry and the potential of the object. According to a second preferred embodiment of the invention, the change in signal due to motion of the sensor in the field produced by the object is minimized by reducing the impact of changes in coupling to the signal source.

Abstract: A system for unobtrusively measuring bioelectric signals developed by an individual includes multiple sensors, one or more of which constitutes a capacitive sensor, embedded into or otherwise integrated into an object, such as a chair, bed or the like, used to support the individual. The object serves as mounting structure that holds the sensors in place. The sensors are preferably arranged in the form of an array, with particular ones of the sensors being selectable from the array for measuring the bioelectric signals which are transmitted, such as through a wireless link, for display and/or analysis purposes.

Abstract: The invention generally pertains to reducing artifact noise signals present when non-invasive capacitive-type signal measurements are taken of static electric fields produced by an object (10) of interest. According to a first preferred embodiment of the invention, a given static artifact signal is reduced by minimizing the potential difference between a ground point (G1) of sensor circuitry and the potential of the object (10). According to a second preferred embodiment of the invention, the change in signal due to motion of the sensor (30, 40; 30?, 40?; 230; 330; 430; 530; 630) in the field produced by the object (10) is minimized by reducing the impact of changes in coupling to the signal source.

Abstract: A system for unobtrusively measuring bioelectric signals developed by an individual includes multiple sensors, one or more of which constitutes a capacitive sensor attached to a holding device. The holding device serves as a mounting structure that holds sensors in place within a wearable garment. The holding device and sensors are horizontally and vertically adjustable relative to the garment, while the sensors are pressed against the individual and prevented from undesirable shifting upon movement of the individual.

Abstract: A system for unobtrusively measuring bioelectric signals developed by an individual includes multiple sensors, one or more of which constitutes a capacitive sensor, embedded into or otherwise integrated into an object, such as a chair, bed or the like, used to support the individual. In one preferred embodiment, multiple capacitive sensors are incorporated into a pad provided in an incubator for unobtrusively measuring bioelectric signals from a baby under supervised care. In any case, the object serves as mounting structure that holds the sensors in place. The sensors are preferably arranged in the form of an array, with particular ones of the sensors being selectable from the array for measuring the bioelectric signals which are transmitted, such as through a wireless link, for display and/or analysis purposes.
