Common mode electronic noise in differential circuits
(2019-07-01)
Article
Restricted access - publisher's policyDifferential circuits are assumed to reject common-mode noise yet no parameter is available to describethat rejection as the Common Mode Rejection Ratio (CMRR) applies only to deterministic signals, not torandom noise. We ... -

Solar energy radiation measurement with a low–power solar energy harvester
(2018-08-01)
Article
Open AccessSolar energy radiation measurements are essential in precision agriculture and forest monitoring and can be readily performed by attaching commercial pyranometers to autonomous sensor nodes. However this solution significantly ... -
Time-Division Multiplexing Control of Multi-Input Converters for Low-Power Solar Energy Harvesters
(Institute of Electrical and Electronics Engineers (IEEE), 2018-03-29)
Article
Open AccessMany autonomous sensor nodes use small photovoltaic (PV) panels oriented towards the direction that provides the highest energy yield in the worst-case scenario. Since all those panels operate at similar irradiance and ... -

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
Open AccessWe 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 ...
