Product Recommendation

Creative Materials’ standard and custom formulations of silver-silver chloride (Ag-AgCl) inks include various ratios of silver and silver chloride. We are able to meet specific customers’ needs for sensitivity and conductivity for producing medical sensors used in biomedical monitoring, diagnostic applications and iontopheretic drug delivery. Creative Materials offers silver-silver chloride inks that are resistant to aggressive chemistries, including methyl ethyl ketone (MEK), demonstrate a resistance to creasing and scratching, and are compatible with high salt content hydrogels.

Applications for our Ag-AgCl electrically conductive inks include ECG, EEG and TENS electrodes; defibrillator pads; transdermal drug delivery; biomedical sensors and reference electrodes. Our silver-silver chloride electrically conductive inks are suitable for application by screen printing, pad printing, syringe dispensing, dipping and spraying as well as by flexographic and rotogravure printing methods and can be applied to a variety of substrates such as polyimide, PEEK, PET, polycarbonate and glass.
