Lab-on-Chip is a technology that could potentially revolutionize medical Point-of-Care diagnostics. Considerable research effort is focused towards innovating production technologies that will make commercial upscaling financially viable. Printed circuit board manufacturing techniques offer several prospects in this field. Here, we present a novel approach to manufacturing Printed Circuit Board...

Electrical impedance tomography (EIT) is a technique used to estimate the internal conductivity of an electrically conductive body by using only measurements from its boundary. If this body is made of a thin, flexible and stretchable material that responds to touch with local changes in conductivity, it can be used to create an artificial sensitive skin. Mathematically, the EIT reconstruction p...

two poly(oxyethylene) derivatives 1.10-bis(2'-benzoic acid)-1,4,7,1-tetradecane (l1) and 1,7-bis(2'-benzoic acid)-1,4,7-trioxaheptane (l2) were used as suitable ionophores for the preparation of potassium-selective pvc-membrane electrodes. the resulting electrodes based on l1 and l2 exhibit linear responses to the activity of k+ ions within the concentration ranges of 3.1´10-5 -2.7´10-2 m and 2...

the electrocatalytic degradation of methyl orange (mo) on pbo2-tio2 nanocomposite electrodes was studied by cyclic voltammetry and bulk electrolysis. the results reveal that pbo2-tio2 nanocomposite electrodes possess higher oxygen evolution overpotential than pbo2 electrodes and the electrocatalytic degradation of mo on the electrodes is direct oxidation process. the influence of experimental p...

sol-gel and polymeric membrane electrodes, based on thiacalix[4]arene as a neutral carrier, weresuccessfully developed for the detection of vo2+ in aqueous solutions. the sol-gel and pvcmembrane electrodes exhibited linear response with nernstian slopes of 29.3 and 28.4 mv perdecade, respectively, within the vanadyl ion concentration ranges from 1.0 × 10-6 to 1.0 × 10-1mol dm-3 and from 1.0 × 1...

wet ag/agcl electrodes, although very popular in clinical diagnosis, are not appropriate for expanding applications of wearable biopotential recording systems which are used repetitively and for a long time. here, the development of a low‑cost and low‑noise active dry electrode is presented. the performance of the new electrodes was assessed for recording electrocardiogram (ecg) and electroence...

The error involved in the use of the equilateral tetrahedron reference system for electrocardiographic or vectorcardiographic studies has been investigated by means of an electrical dipole placed in the esophagus. Vectors plotted from the potential differences between electrodes defining the reference system were found to correspond fairly closely to the actual position of the dipole, indicatin...

The performance of four methods for interpolation of body surface potential maps (BSPMs) for different electrode grid densities was assessed. This study is part of a research project on the influence of the variability of 12-lead electrocardiograms on computer interpretation due to small electrode position changes. Interpolated BSPMs can be used to simulate this variability. The set of BSPMs st...
