Since “ST-gel” has a good level of stability when measuring, it's used as a conductive adhesive for bioelectrodes in many medical fields.
In addition to selling “ST-gel” as a gel material, our company has built a consistent production system up to the processing stage of finished products such as electrodes, adhesive pads etc., and we have a track record as a design business, a manufacturing business, and a manufacturing and sales business of medical equipment.
We can perform customization based on various cases. Please feel free to contact us.
Structure and Electrical Performance of “ST-gel”
Since “ST-gel” contains moisturizers and electrolytes in the polymer matrix that forms the gel, it exhibits various characteristics including adhesiveness, dry resistance, conductivity etc. An electrode which combines “ST-gel” and an electrode element can be adhered stably onto the skin, it can sense a minute current using its conductivity, and it can flow a current generated by the device through to the human body.
Example of Measurement by an ECG Electrode Using “ST-gel”
Disposable electrodes used for electrocardiogram examinations. Conforms to AAMI/ANSI EC 12 which is the standard for medical equipment in the United States.
| Characteristics of Electrocardiogram Electrodes | AAMI (United States Association for the Advancement of Medical Instrumentation) Standards | Measurement Example |
|---|---|---|
| Electrode Pair Impedance (Ω) | 2000max.avg | 150 |
| Electrode Pair Voltage (mV) | 100max. | 0.5 |
| Defibrillation Tolerance (mV) | 100max. | 15 |
| Defibrillation Tolerance (mV/sec) | 1max. | 0.2 |
| Electrode Pair Impedance (Ω) after Defibrillation Tolerance Testing | 3000max. | 130 |
Medical Equipment (Response to Pharmaceutical Affairs)
We are carrying out the design, development and manufacturing, and quality control of various bioelectrodes which conform to the QMS ministerial ordinance.
We have a track record of support such as providing technical data for CE mark acquisition and FDA acquisition. Please contact us.
Processed “ST-gel” Products for Medical Applications
Electrocardiogram Electrodes
Low impedance allows stable electrocardiographic measurements. There is a lineup of electrodes with soft adhesion and excellent conformability to the skin.
Return Electrodes for Electrosurgical Instruments
A return electrode (earth electrode) used for surgery which utilizes an electric scalpel (electrosurgical instrument). There are conductive-type and electrostatic capacitive-type return electrodes, and we have return electrodes in a variety of sizes for everyone from adults to extremely low-weight babies to accommodate different patient weights.
ECG Electrodes for Examinations
We offer resting ECG electrodes (electrodes for electrocardiogram examinations). Employs a gel material (HIT grade) which demonstrates adequate adhesiveness even in small areas. High adhesiveness is demonstrated immediately after being adhered to the skin which allows a stable examination.
Electrodes for Electrical Stimulation Devices
We offer electrodes and gel pads used for electrical stimulation devices such as TENS, EMS, etc. Can be used repeatedly without a sense of irritation caused by passing the electric current.
Gel Taping
It is a taping that is used for purposes of fixing, relieving pain, etc. Since taping which uses “ST-gel” is gentle on the skin and imposes less chance of causing a rash, it can be used for those who have sensitive skin and cannot use standard taping. Also used in research into preventing locomotive syndrome.
New Approaches to Expand the Fields of Usage of “ST-gel”
An Example of a New Approach, Advanced Medical Care
In recent years, there has been much research conducted on the brain in advanced medical care. “ST-gel” has also been adopted in the advanced medical field.
