Multisensor system for analyzing the thigh movement during walking
(2017-08-01)
Article
Open AccessBody movements monitoring may allow preventing, diagnosing, and recovering several wrong attitudes that could lead to possible future diseases. A multisensor system was developed to measure thigh movements in free-living ... -
On the feasibility of noncontact ECG measurements
(2016-03-01)
Article
Open AccessThe article by Kranjec et al. [1], “Novel methods of noncontact heart rate measurement: A feasibility study” is interesting and informative as it compares different contactless methods for heart rate detection. Nevertheless, ... -
The QT scale: a weight scale measuring the QTc interval
(Wiley, 2017-01)
Article
Open AccessDespite the strong evidence of the clinical utility of QTc prolongation as a surrogate marker of cardiac risk, QTc measurement is not part of clinical routine either in hospital or in physician of fi ces. We evaluated ... -
On bio activity related signals from contactless electrode measurements
(2016-02-01)
Article
Open AccessIn a recent paper on a displacement current sensor for contactless detection of bio-activity related signals [1], it was stated that “A potential means for human presence detection…is via sensing…human biopotentials” ... -
Low-power direct resistive sensor-to-microcontroller interfaces
(2016-01-01)
Article
Open AccessThis paper analyzes the energy consumption of direct interface circuits where the data conversion of a resistive sensor is performed by a direct connection to a set of digital ports of a microcontroller (µC). The causes ... -
Entropy characterisation of overstressed capacitors for lifetime prediction
(2016-12-30)
Article
Restricted access - publisher's policyWe propose a method to monitor the ageing and damage of capacitors based on their irreversible entropy generation rate. We overstressed several electrolytic capacitors in the range of 33 µF–100 µF and monitored their entropy ... -
An algorithm for beat-to-beat heart rate detection from the BCG based on the continuous spline wavelet transform
(2016-05-01)
Article
Open AccessThis work describes an algorithm intended to detect the beat-to-beat heart rate from the ballistocardiogram (BCG) obtained from seated subjects. The algorithm is based on the continuous wavelet transform with splines, which ... -
Calibration-less direct capacitor-to-microcontroller interface
(Institution of Electrical Engineers, 2016-02-18)
Article
Open AccessA new technique to measure a capacitor or a capacitive sensor by means of a direct sensor-to-microcontroller interface circuit that does not need a calibration capacitor is proposed. Basically, the measurement process ... -
A novel method to obtain proximal plethysmographic information from distal measurements using the impedance plethysmogram
(University of Oslo, 2015-12-23)
Article
Open AccessWe present a novel method to detect proximal volume changes based on the impedance plethysmogram (IPG) measured from limb to limb with two electrode pairs symmetrically placed at distal areas of the upper or the lower ... -
Design of a low-cost wireless sensor network with UAV mobile node for agricultural applications
(2015-11-01)
Article
Restricted access - publisher's policyThe aim of the present paper is to propose an agricultural environment monitoring server system utilizing a low-cost Wireless Sensor Network (WSN). Several sensor nodes are scattered in fields several kilometres in size, ... -
Ballistocardiography and Seismocardiography: A Review of Recent Advances
(2015-07-01)
Article
Open AccessIn the past decade, there has been a resurgence in the field of unobtrusive cardiomechanical assessment, through advancing methods for measuring and interpreting ballistocardiogram (BCG) and seismocardiogram (SCG) signals. ... -
Smart lighting system ISO/IEC/IEEE 21451 compatible
(2015-05-01)
Article
Open AccessSmart lighting systems go far beyond merely replacing lamps. These modern systems are now able to reproduce arbitrary spectra, color temperatures, and intensities and pivot on smart sensors and actuators incorporating ...
