摘要: In order to realize heart rate monitoring on a bed, there are mainly two types of approaches similar other signal processing applications: frequency domain analysis and time-series analysis. analysis, FFT is widely used extract from obtained signals. Since assumes constant frequency, it cannot be for extracting microscopic variability rate. pattern matching based autocorrelation commonly used. The method not only advanced in sensitivity variability, but also sensitive unexpected noise. response these problems, technology proposed by using air pressure sensor. this paper, estimation algorithm employing fuzzy logic effectiveness applied biomedical sensing discussed. experiments were conducted validate the comparing with methods such as autocorrelation.
