BioMediTech Research Groups

Nanoscale Phenomena and Measurements

Group Leader: Associate Professor Sampo Tuukkanen


About Us

The mission of the Nanoscale Phenomena and Measurements (NPM) research group is to measure, understand and exploit the nanoscale phenomena occurring in bio-based nanomaterials and devices. Developed biomaterial structures and devices are widely applicable for biomedical applications.

Research interests and expertise

Recent research topics are:

  • Piezoelectric sensors
  • Supercapacitors
  • Energy harvesting and storage systems
  • Biomedical microdevices
  • Biomeasurements
  • Processing and characterization of nanomaterial and biomaterials
  • Scalable manufacturing using printing techniques


  • Piezoelectric sensitivity measurement system
  • Equipment for electrical and electrochemical measurements
  • Multi-material biomaterial printing equipment (for various plastic and biological materials)
  • Freeze-drier equipped with heat-controlled shelf in the chamber

Collaboration offer and requests

We offer knowledge and equipment for multi-material bio-printing as well as electrical and structural characterization of components and devices.
