RF electronics design involves PCB level circuit design with focus on simple and low-cost solutions.


Current research projects

Electromagnetic modeling in the printable electronics design flow

8/2008-7/2013 (Academy of Finland). Contact: Riku Mäkinen

The research focuses on the use of EM simulation to establish electrical guidelines (e.g. re­quired conductivity and layer thickness) for printable electronics applications, and with empirical data on the manufacturing process, use this information to select proper manufacturing process and process parameters that meet the electrical specifi­cations. EM simulation is also applied to design new applica­tions that are optimized for the manufacturing technology.

Parallelized electromagnetic modeling envi­ron­ment for large-scale printable electronics applications

1/2009-12/2012 (Academy of Finland). Contact: Riku Mäkinen

Efficient grid-based tech­niques based on sur­face-im­pedance con­cepts to model arbitrarily-shaped lossy thin, penetrable conductors are de­vel­oped for the explicit time-do­main methods. Developed models will be suitable for parallelization, and a par­allelized environment based on MPI, PETSc, and SLEPc software libraries is developed to cope with realistic problems and is subse­quently applied to the design and analysis of non-planar 3-D printable elec­tronics applications.

Flexible Electronics for Smart Environment: Wireless Sensor Platform (Flexwise)

7/2010-6/2012 (Tekes, the Finnish Funding Agency for Technology and Innovation). Contact: Riku Mäkinen

Flexible electronics manufacturing concept based on printable electronics technology is developed and applied to design wireless sensor applications. Research concentrates on evaluation (RF electrical performance, environmental testing) of flexible electronics materials such as polymer film substrates and conducting nanoparticle inks as well as integration of electronics components on a flexible substrate. Key design tasks involve printable RF and antenna design. Applications include a flexible wireless sensor for smart sail as well as wearable, stretchable electronics applications.
