Non-invasive respiratory monitoring using long-period fiber grating sensors.
In non-invasive ventilation, continuous monitoring of respiratory volumes is essential. Here, we present a method for the measurement of respiratory volumes by a single fiber-grating sensor of bending and provide the proof-of-principle by applying a calibration-test measurement procedure on a set of 18 healthy volunteers. Results establish a linear correlation between a change in lung volume an...
متن کاملNon-Contact Detection of Breathing Using a Microwave Sensor
In this paper the use of a continuous-wave microwave sensor as a non-contact tool for quantitative measurement of respiratory tidal volume has been evaluated by experimentation in seventeen healthy volunteers. The sensor working principle is reported and several causes that can affect its response are analyzed. A suitable data processing has been devised able to reject the majority of breath me...
متن کاملNon-contact Photoacoustic Tomography using holographic full field detection
An innovative very fast non-contact imaging technique for Photoacoustic Tomography is introduced. It is based on holographic optical speckle detection of a transiently altering surface topography for the reconstruction of absorbing targets. The surface movement is obtained by parallel recording of speckle phase changes known as Electronic Speckle Pattern Interferometry. Due to parallelized 2-D ...
متن کاملSecure Detection Using Binary Sensors
Cyber-physical systems employing remote sensors and actuators and sparse communication networks are pervading the infrastructure. In this paper we consider a prototypical problem of estimating a binary state using measurements provided by binary sensors. We propose a new approach to estimate the states based on sensor measurements that may have been corrupted by an attacker. The problem is form...
متن کاملInfluence of background noise on non-contact vibration measurements using particle velocity sensors
ABSTRACT Structural vibrations are usually measured using accelerometers or laser Doppler vibrometers. However, the weight of the accelerometers can influence vibration patterns and lasers can have problems with non-reflective or fibrous materials. Alternatively, vibration can also be measured acoustically using particle velocity sensors positioned near the structure. Although the capabilities ...
