Reusable flexible dry electrodes for biomedical wearable devices

Sensors and Actuators A: Physical, 2022
Abstract This paper reports the fabrication and the characterization of novel reusable Flexible Dry Electrodes (FDEs), which can be employed in wearable devices for medical applications, such as bioelectrical impedance analysis (BIA). Two different FDEs were fabricated exploiting two flexible substrates, i.e.

Development of a miniaturepCO2 electrode for biomedical applications

Medical & Biological Engineering, 1975
A miniaturepCO2 electrode for possible CO2 measurement in a biological system was constructed and evaluated. ThepCO2 electrode employed a miniature pH glass electrode and the Severinghaus configuration. The electrode was evaluated in both gas and liquid phases. A good linear relation existed between the measured electrode potential of thepCO2 electrode

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

Impedance Characterization and Modeling of Electrodes for Biomedical Applications

IEEE Transactions on Biomedical Engineering, 2005
A low electrode-electrolyte impedance interface is critical in the design of electrodes for biomedical applications. To design low-impedance interfaces a complete understanding of the physical processes contributing to the impedance is required. In this work a model describing these physical processes is validated and extended to quantify the effect of

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.

Numerical Modelling of Capacitive Electrodes for Biomedical Signals Measurement

2021 44th International Convention on Information, Communication and Electronic Technology (MIPRO), 2021
Surface electromyography (sEMG) uses noninvasive technique of measuring muscle action potentials on the skin surface. Numerical methods are often the first step in such a process of electrodes and biomedical electronic systems design. Thoughtful simulation, that precedes physical implementation, may speed up the product development, foreseeing its ...

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.

INVESTIGATION ON BIOMEDICAL MEASUREMENT ACCURACY IN ELECTRODE-SKIN TESTS

IFAC Proceedings Volumes, 2006
Abstract The paper investigates three sources of potential error in measurements that may be taken as part of a clinical protocol using Electrical Impedance Tomography (EIT). The findings of an investigation show that the error of two types of electrode used (Stainless Steel and ECG) could produce 13.5-44.5%, 1.5-34.8% and 9.9-83.7% errors in ...

Titanium dioxide nanowires-based interdigitated electrodes for biomedical application

2012 IEEE-EMBS Conference on Biomedical Engineering and Sciences, 2012
It has been tremendous attention to use titanium dioxide (TiO 2 ) as a material for biosensing application. TiO 2 is one of the n-type semiconductor materials with the energy gaps are between 1.8 and 4.1 eV. Nanowires TiO 2 will be growth via sol-gel method and combination of TiO 2 nanowires with fabricated interdigitated electrodes (IDEs) can form ...
