Hans Johrend

I’m a mechatronics engineer and researcher from Cluj-Napoca, passionate about hardware and the intersection of physics and engineering.

Currently pursuing an MSc in Solid State Physics where I build devices for prototyping low cost microelectronics.

To this date I have worked on hardware R&D projects in both the private sector and academia, projects which span from robotics, assistive technologies to custom manufacturing systems.

I specialize in hardware design, embedded systems, rapid prototyping and additive manufacturing technologies.
