Designing Conductive Inks for the Market: Bio & eHealth

Celanesae Micromax | presested live onsite in Eindhoven in OCT 2022

This is an AI-generated summary of the talk

  • There are a lot of different applications for biosensors, such as blood glucose measurement, drug delivery, DNA testing, food and beverage testing, and environmental sensors. I think the list can be extended to include blood gas detection or measuring urine detection.

  • Blood glucose test strips are used to measure blood glucose levels. The next generation is the continuous glucose monitoring patch, which doesn't require you to take a drop of blood many times over the day.

  • The principle is the same as a blood glucose test strip, but the needle goes in the skin not so deep, but going into the skin, and it measures the diffused glucose in the interstellar fluid in the skin. The electrocardiogram is a simple description of a muscle contraction. It is used in wellness applications as well as medical applications, and therefore the material must really constant and that starts to be really challenging.

  • I think the principle is always the same, and you can measure an electrical impulse in many parts of the body.

  • The design of an ECG electrode is that you have a single disposable patch, and typically use silver, silver chloride electrodes. However, the gel can cause skin irritation, and the patch is limited in the shelf life or the usable time.

  • We are not only focused on ECG and blood glucose, we are also working on other products. The key word is partnership, and the more information we have, the better it is for us to create and design products for it.

  • Partnership from the beginning, understanding what is needed and first the application itself, and then the manufacturing conditions which are typically more more familiar with us, is an important step or thing. The latest developments at the moment and where we are working on include improving pay, stability, longer screen life and so on.

  • Here is a list of different solvents, and we concentrate very often on thf because if a paste is resistant to thf it covers most of the other solvents which could be there. And now I give you an impression what we are doing.

  • We are improving our products and formulating new products, and a new tendency is going to more cross-linked formulations. These inks dry at lower temperatures, and can be used on other substrates.

  • The cross-linking is done after printing, drying, and taking it off the pet. It gives a better adhesion and resistance against mechanical stress, and on one hand it's more acid and solvent and whatever resistant

  • We are developing pastes for the blood glucose and ag market, and the newest one is some cross-linked compositions for more abrasion resistance, hydrogel stability or other solvents.

  • For biosensor business, it's really difficult to say. It's depending how many iterative steps you need, and if you're talking about medical applications, where really everything must work under every condition and you must be absolutely safe, or if you are more in the wellness area.
