Great opportunities exist for Ion-Selective Electrodes (ISEs) in the fields of environmental monitoring and of wearable applications for example as the sensing part in wireless networks. In this review special attention is given to the recent results obtained with Solid Contact IonSelective Electrodes and Solid Contact Reference Electrodes. Their combination as disposable sensing platform may o...

The response time of thermal electrolytic Ag/AgCl reference electrodes is defined by the porous structure that limits the rate at which traces of any previous solution are diluted by any new solution environment. The electrode stabilisation time when transferred from one electrolyte to another has been shown to change when different structural designs to the conventional sphere of Ag/AgCl are u...

We present a new, low-power electrocardiogram (ECG) recording system with an ultra-high input impedance that enables the use of long-lasting, dry electrodes. The system incorporates a low-power Bluetooth module for wireless connectivity and is designed to be suitable for long-term monitoring during daily activities. The new system using dry electrodes was compared with a clinically approved ECG...

background existence of fluoride in drinking water above the permissible level causes human skeletal fluorosis. objectives electrocoagulation by iron and aluminum electrodes was proposed for removing fluoride from drinking water. materials and methods effects of different operating conditions such as treatment time, initial ph, applied voltage, type and number of electrodes, the spaces between ...

Electrochemical techniques rely on the stability of a defined reference potential. Due to the need for miniaturization, electrochemical lab-on-a-chip platforms often employ Ag/AgCl quasi-reference electrodes for this purpose. Here, we report on electrochemical artifacts resulting from nanoparticle-electrode collisions originating from standard chlorinated silver wires.

Mapping of electrical endocardial activity is an important procedure for cardiac diagnosis and surgical treatment planning. The measurement is usually done using single string catheters with a limited number of electrodes. In recent years an increasing number of mapping systems is used in clinical routine. Different systems have been introduced and discussed in literature [1][2]. These systems ...
