INCONTROL MEDICAL ELECTRODE GEL SERIES

To those of you whom have waited patiently we THANK YOU!!! We promise you that we will get your product out as quickly as we can. As a small business this has had a huge impact on getting the product shipped out and we never expected it to be such a long wait. We are anticipating having these alternatives in place within the next 2 weeks. We just wanted to check in with you to let you know that we do still have your order and we know it has been a very long time, but we are just not having luck getting what we need! We are in the process of looking for alternatives since we have been severely let down by our current vendor who has caused us to stop production due to the inability to finish our product. Only received on correspondence in May of 2022 from a ************************* with the email below. CPE and R d are determined by the property of the stratum corneum between the metal electrode and the underlying tissue.I ordered Feb 2022. R s is associated with the resistance of the wire, conductive gel, and sweat.

This model is represented by a resistor R s in series with a parallel combination of a CPE and a resistor R d. c The simplified Cole system electrical equivalent model of electrode–skin interface because the impedance of the electrode–conductive gel interface is much smaller than that of the stratum corneum. The underlying (living) tissue is modeled by a resistor R t.

The stratum corneum is represented by a resistor R sc in series with a parallel combination of a CPE Y sd and a resistor R sd.

The electrode–conductive gel interface is represented by the resistor R eg in series with a parallel combination of a constant phase element (CPE) Y ei and a resistor R ei.

b Equivalent model of electrode–skin-underlying tissue. a Electrode–skin-underlying tissue composite. Results showed that combination of Ag +/Ag +Cl - powder electrode and low viscosity conductive gel performed best overall (Ten 20 ® in this study) it had a relatively low magnitude of contact impedance and superior performance regarding contact impedance with time (p < 0.05) and frequency (p < 0.05).Įxperimental results indicates that the combination of Ag +/Ag +Cl - powder electrode and low viscosity conductive gel may be the best choice for brain EIT.īrain EIT Combination Conductive gel Electrode.Ĭomposite of the electrical equivalent model of electrode–skin-underlying tissue. And then the performance of each combination was systematically evaluated in terms of the magnitude of contact impedance, and changes in contact impedance with time and frequency.

In this study, the contact impedance of 16 combinations consisting of 4 kinds of clinical electrode and five types of commonly used conductive gel was measured on ten volunteers' scalp for a period of 1 h at frequencies from 100 Hz to 1 MHz using the two-electrode method. To our knowledge, no study has simultaneously investigated the time and frequency properties of both electrode and conductive gel for brain EIT. The time and frequency properties of electrode-skin contact impedance are important for brain EIT because brain EIT measurement is performed over a long period when used to monitor brain injury, and is carried out across a wide range of frequencies when used to detect stroke. Electrical impedance tomography (EIT) is an emerging imaging technology that has been used to monitor brain injury and detect acute stroke.
