Estimated reading time: 3 minutes
In our latest webinar, the spotlight was on printing biomedical sensors using NOVA technology, a landmark in the evolution of printed electronics. We also highlighted Creative Materials’ 124-36 Ag/AgCl (silver silver-chloride) ink, which was perfect for the application we demonstrated.
Precision materials dispensing
The webinar focused primarily on the precision and adaptability of NOVA in printing biomedical sensors. With the use of advanced materials and sophisticated printing techniques, made easier with products like NOVA and Creative Materials inks, you’re able to create sensors that are both highly functional and biocompatible.
Printing techniques explored: We discussed various methods like syringe dispensing and screen printing, emphasizing their relevance in biomedical applications.
Material compatibility: The webinar highlighted the compatibility of NOVA with a range of materials, including innovative silver/silver-chloride inks.
Flexibility: Customization became a key theme, with discussions in the live chat of the webinar on tailoring sensor designs to specific biomedical needs and the flexibility of materials on different substrates.

Audience Q&A insights
Ink selection: One question inquired on the difference between pure silver inks and silver/silver-chloride inks. Our experts explained that while pure silver offers higher conductivity, silver/silver-chloride inks provide greater biocompatibility, crucial for sensors in direct contact with skin.
Printing on flexible materials: A question arose about NOVA's ability to print on flexible substrates and we clarified that NOVA's precision and pressure feedback dispensing make it ideal for such applications, above and beyond the capability of the V-One.
Ink preparation and handling: Questions about ink preparation underscored the importance of proper material handling for optimal printing results. Many helpful tools and techniques were highlighted, including but not limited to:
- A planetary mixer to help blend materials to ensure a complete mix and consistent flow.
- Deflection testing to identify whether there’s air in the dispenser, which is further helped by the pressure feedback from NOVA’s Smart Dispenser.
- Consultation with experts (like Creative Materials) for recommendations when you’re looking to create custom mixed materials for your application.
A significant portion of the webinar was dedicated to a live demonstration, showcasing the printing of a biomedical sensor using NOVA. This hands-on display not only highlighted the machine’s capabilities but also addressed practical considerations like setup time and material preparation.
