Digital health


Driving health innovation through technology excellence

We help our customers develop new technologies and service concepts in the area of Digital health – and support their growth with top-level research and science-based results. Together with our customers, we want to give a contribution to affordable and high-quality care through technology innovation. The results can be seen as improvements in preventive healthcare, predictive diagnostics and care, as well as health care process optimization.

Our pragmatic approach stems from a deep knowledge of the medical sphere combined with state-of-the-art engineering competences. Turning opportunities into a success requires a combination of high-quality R&D in medical sciences, ICT, wearable sensors and in diagnostics technologies. In addition, to further make the life of our customers easier, we offer early-stage clinical validations of developed technology solutions. This is why VTT works in agile cross-technology teams, helping our customers in creating unique solutions.

AI enables smart health technologies and solutions

Ensuring high quality of care for the entire population with manageable costs requires that healthcare systems are re-defined and new methods for advancing personal health and empowering self-care are developed. AI enabled technologies will help to optimise health care processes for ultimate resource efficiency. Smart usage of data, taking the privacy and confidentiality aspects into consideration, will be in a decisive role in future health management. As part of the Finnish smart health ecosystem, VTT actively promotes the utilization of Finland´s unique health data repositories for creating innovations in data-driven precision medicine, e.g. Smart Health ecosystem event on 12 June in Helsinki and Premed ecosystem.

Human data analysis 

Data mining is one of our core capabilities. It involves data mining, bio-signal and medical image analysis, systems medicine and other relevant methodologies that aid us in discovering and developing innovative solutions for early diagnostics and effective disease therapies. The human body is an extremely complex system, and therefor reliable clinical decision-making demands a holistic view. We take a multidisciplinary approach to developing automated and objective analysis tools for clinical practice. Our mission is to transform heterogeneous, complex health data into information that helps health care professionals to make better decisions.

​Medical imaging equipment to diagnose skin cancer

Customer: Medlumics

Challenge: Reducing the size and cost of optical coherence tomography (OCT) systems.

Solution: VTT provided silicon photonics technology which is based on 3 µm thick Si waveguides that form photonic integrated circuits on small Si chips. Commercial manufacturing was started via VTT Memsfab.

Key benefits:

  • Ready prototype of OCT using silicon photonics technology 
  • Unique combination of low loss, broadband and polarisation independent operation, as well as ultra-dense integration, low cost and industrial manufacturability.
  • Medlumics is now ready to develop portable and affordable OCT systems for medical imaging.


" VTT’s low-loss photonic platform is helping us improve our medical virtual biopsy products by miniaturizing all the optics into a tiny chip, thus reducing size and cost of what are otherwise complex systems. We have found a strong commitment to quality procedures and reliable fabrication, which has been fundamental for our success in moving towards a commercial product."

Eduardo Margallo, CEO, Medlumics
