Noise countermeasures for electrocardiograms: Biopotential electrode film SilkyLink
SilkyLinkⓇ
Electrode film that reduces impedance with the skin.
There is a lot of noise in electrocardiogram measurements, and the signals are unstable—one of the causes is the skin-electrode impedance. The MFX-1100 maintains low impedance over a long period due to its Ag/AgCl electrode layer, supporting stable measurements. SilkyLink MFX-1100 is a thin and flexible electrode material formed with a silver/silver chloride (Ag/AgCl) electrode layer on a conductive polyurethane film. It can be cut and punched into the required shapes, allowing for prototype and product development without the need to build in-house processes for electrode formation such as paste mixing, printing, and drying. While silver/silver chloride paste (Peltron K-398X) allows for "free printing and creation," SilkyLink is characterized by being "pre-formed with functional layers and ready to use." It can be handled at low temperatures and is suitable for a wide range of applications, from electrocardiograms and electromyograms to electroencephalograms and defibrillation pads.

basic information
【Do you have such needs?】 ○ There are issues with the stability, quality, and cost of the current electrode film supply. ○ I want to develop electrodes that can follow body movements. ○ I want to keep the electrodes attached during X-ray examinations. ○ I want to easily cut the electrodes to the necessary size and shape. 【Features of this film】 ・Maintains low skin-electrode impedance even with long-term use. ・Can be used for X-ray imaging without using metal foil as the main substrate (internal evaluation). ・High adhesion of the silver/silver chloride coating, making it difficult to peel off. ・High flexibility with a polyurethane substrate, allowing it to follow human body movements. Representative specifications: Substrate polyurethane / Total thickness approximately 103μm / Ag/AgCl electrode layer approximately 3μm / Surface resistance approximately 0.8Ω/sq *All values are representative. Official specifications, measurement methods, and warranty scope will be provided in individual technical documents.
