Heart Man

HeartMan is a research project funded by the European Union’s Horizon 2020 programme that is developing a personal health system to help congestive heart failure patients manage their disease.

HeartMan will provide accurate advice on disease management adapted to each patient, and it will do so in a friendly and supportive fashion.

The project started in 2016 and will finish in 2019. More info: http://heartman-project.eu/.

A European consortium led by Jožef Stefan Institute has launched HeartMan. The project partners are Sapienza University, Ghent University, National Research Council, ATOS Spain SA, SenLab, KU Leuven, MEGA Electronics Ltd and European Heart Network.

We are a group of researchers interested in using advanced technology to improve the society, and companies with extensive experience in the health market.

We know that we not only have to develop a research prototype, but must a reliable and affordable system that respects health and privacy regulations. We have this goal in mind from day one, and are confident we can achieve at the end of the project.

  • Interdisciplinary research on complex functional materials and nanometer-scale structures, exploration of physical, chemical, and biological principles, their exploitation in integrated micro- and nanosystems, and in the development of characterization techniques.
  • Dissemination of the results in international programs, education and industrial R&D, with special attention to the needs of SMEs.


Development of the following sensors and devices:
i) 3D MEMS force sensors in “smart laparoscope” and its first application in Minimal Invasive Surgery robot
ii) Development autonomous microfluidic systems for Lab-on-a-Chip based Point-of-Care medical diagnostics in cooperation with industrial partners
iii) Wafer scale integration of piezoelectric semiconductor nanowires and demonstration of the proof-of-concept of very high resolution 3D tactile sensing.

A novel device concept based on the world-first experimental realization within our institute of sub-10nm zigzag graphene nanoribbons was suggested which enables the control of both charge and spin signals.
A novel oxidation process of 2D MoS2 crystals was discovered, which is an efficient catalyst of the hydrogen evolution reaction, due to the single oxygen atom sites incorporated into the lattice.

New biocompatible coatings were developed for human implants with very high bioactivity realized by powder technology from eggshells and seashells, as well as Si3N4 based ceramic composites with graphene addition with 2 times lower wear.
A micro-combinatorical method was developed (and patented), which allows the study and testing of a linearly variable composition of materials co-deposited on the single 3 mm sized TEM grid.

A bacteria repellent layer based on oriented flagellin films was developed. They have successfully employed a label-free optical biosensor for on-line monitoring the integrated response of human B cells upon the engagement of stimulatory and inhibitory immune receptors.

Successful development of cutting-edge methods and tools for the non-destructive optical and magnetic characterization of materials and surface nanostructures including spectroscopy, magnetic test, topography characterization and sensors for water pollution.

In the field of sociophysics and evolutionary games the statistical physics group described different mechanisms (punishment, information sharing, collaborations, etc.) which help the societies to maintain the cooperative behavior. The relevance of Griffiths phases is justified for several systems including energy grid analysis
