Measuring Respiration Rate Via Android

Measuring Respiration

The measurement of respiration is very important because it provides a window through which we can determine the metabolic activity of plant tissues. During aerobic respiration, stored food (e.g., carbohydrates, fats, proteins) are combined with oxygen from the atmosphere to produce carbon dioxide, water and the energy needed to maintain the plant cell, tissue and quality of the commodity. The ...

Measuring Respiration and Heart Rate using Two Acceleration Sensors on a Fully Embedded Platform

We present a novel system which measures the respiration rate using two three-axis accelerometers strapped to the chest and the back of a person. Respiration and heart rate are used as a measurement to determine an athlete’s fitness level during the exercise phase. Common respiration rate measurement methods require devices which are mostly stationary or at least clunky and uncomfortable to wea...

Data Fusion for Improved Respiration Rate Estimation

We present an application of a modified Kalman-Filter (KF) framework for data fusion to the estimation of respiratory rate from multiple physiological sources which is robust to background noise. A novel index of the underlying signal quality of respiratory signals is presented and then used to modify the noise covariance matrix of the KF which discounts the effect of noisy data. The signal qua...

Temperature affects respiration rate of Oithona similis

Oithona spp. is considered the most abundant and ubiquitous copepod genus in the marine environment, often outnumbering calanoid copepods throughout the year. Previous studies have argued that one of the reasons for such success is that the respiration rate of Oithona spp. is insensitive to temperature changes and lower than in calanoids. However, comprehensive data on the thermal biology of th...
