Ion-Selective Electrodes in Biomedical Analysis

C R C Critical Reviews in Analytical Chemistry, 1982
I. INTRODUCTION AND SCOPE The ion-selective electrode is an electrochemical sensor characterized by a selective response to a particular ionic species. The wording “selective” rather than “specific” is considered since it is very rare that an electrode responds to a single ion exclusive of all others. The ion-selective electrode is further described as

Controlled metallic nanopillars for low impedance biomedical electrode

Acta Biomaterialia, 2014
Radial metallic nanopillar/nanowire structures can be created by a controlled radiofrequency (RF) plasma processing technique on the surface of certain alloy wires, including important biomedical alloys such as MP35N (Co-Ni-Cr-Mo alloy), platinum-iridium and stainless steel.

Mechanical characterization of biomedical electrode on knit textile

2016 Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS (DTIP), 2016
The wearable biomedical devices require mechanical stretchability to follow the motion of the human body. We have developed highly stretchable electrode made of knit textile. In this report, we investigated the stretchability of the knit biomedical electrode.

Biomedical Electrode

Electrodes are essential tools in biomedical engineering because they serve as interfaces between biological systems and electronic measurement instruments, transforming bodily ionic currents into electrical signals that can be measured. These signals such as those from the muscles (EMG), brain (EEG), and heart (ECG) are crucial for the diagnosis and ...

Flexible PET/ITO electrode array for implantable biomedical applications

2011 Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2011
Flexible PET/ITO (PolyEthylene Terephthalate/ Indium Tin Oxide) implantable electrode array for spinal cord stimulation and retina prosthesis have been developed. The electrode array is fabricated on a thin PET/ITO substrate and encapsulated with insulating material, SU-8. The PET substrate made electrodes flexible so that they could shape to contoured

Applications of Miniature Electrodes to Biomedical Studies

1985
Beginning in the 1970s our laboratory began applying modern electroanalytical techniques to problem-solving in neurochemistry and neurobiology--particularly the determination of biogenic amines and related substances both in vitro and in vivo. The in vivo approach utilizes very small graphite electrodes implanted in brain tissue to directly detect ...

An Electrode Impedance Balanced Interface for Biomedical Application

2017
This work reports on the design of an electronic interface performing biomedical signal measurements. The proposed system involves three functional blocks: two leading electrodes, the signal conditioning front-end and a feedback circuitry. In particular, the latter is able to balance the electrodes impedance mismatching so to reduce the noise ...

Single-Transducer Electrode Design for Beam Shaping in Biomedical Ultrasound

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1986
Abstruct-Single-electrode single-frequency continuous-wave transducers (radius 1.9 cm, frequency 1.7 or 1.75 MHz) were developed for producing desired circularly symmetric lateral intensity profiles at specified axial distances in water. The methods can be used to produce a variety of intensity profiles.

Challenges in biomedical signals monitoring using textile electrodes: A review

Computers and Electrical Engineering
The continuous monitoring of biosignals plays a crucial role in identifying and addressing serious health conditions. Conventional silver/silver chloride (Ag/AgCl) electrodes, typically used for measuring biosignals, pose challenges for extended monitoring due to their tendency to dry out and cause skin irritation over time. Textile electrodes (TE) are
