- A novel wearable sensor device for continuous monitoring of cardiac activity during sleepInfoDetails
J. Schneider and M. Schroth and J. Ottenbacher and W. Stork, 2018
The miniaturization and energy optimization of sensors opens up new possibilities in the field of sleep research. Wearable sensors are capable of recording vital parameters during sleep in a simple and unobtrusive manner. In order to analyze sleep architecture and sleep disorders, continuous monitoring of movements and cardiorespiratory parameters in high resolution is of central importance. In this paper a novel wearable sensor device based on impedance plethysmography (IPG) is presented, which is able to continuously monitor movements and cardiac parameters at the wrist. The sensor is designed to realize high resolution measurements up to 48 hours constantly. Measurements during sleep show that up to 98% of the pulse intervals are correctly detected. Furthermore, the comparison of the heart rate variability (HRV) parameters between IPG and the gold standard ECG demonstrate the potential of the sensor as a valid tool for ambulant sleep analysis.
- An approach to improve impedance plethysmography on the wrist by using adaptive feedback controlInfoDetails
J. Schneider and M. Schroth and M. Holzhey and T. Blöcher and W. Stork, 2017
The growing market of wearable devices made ambulant vital sign monitoring popular in recent years. Impedance plethysmography (IPG) provides a promising low power solution for detecting pulse waves and respiration by measuring the impedance of blood vessels at the wrist. However, the measurement principle makes high demands on the analog front end, due to low signal-to-noise ratio (SNR) and unknown measurement conditions. In this paper an approach to apply impedance plethysmography is presented. The proposed circuit is based on the impedance measurement IC AD5933 and an adaptive feedback control to regulate current injection and measuring amplification in order to adjust the optimal operating point. Experimental studies demonstrate the potential of the system as promising technology for continuous vital sign monitoring on the wrist.
