36 DESIGN007 MAGAZINE I MARCH 2018 Kolk: I started at the university in R&D, then I moved to engineering companies and spent 15 years at EMS companies in different parts of world. Shaughnessy: Is there anything else you would like to talk about? I think Americans need to know more about this part of the world. Kolk: Again, in IT, we have many success sto- ries in Estonia. Skype was first developed in Estonia, for instance, and there are now more unicorns (private companies worth $1 billion) coming up, so we try to repeat the same suc- cess in electronics as well. There are some rather promising young companies now. For example, there is one company called Skele- ton Technologies. They have developed some supercapacitors that are record breaking. They have one factory in Estonia, and they have built a new one in Germany for all the automo- tive and aerospace business. There are some other crazy things now on the boundaries of different sectors. For exam- ple, an Estonian company called Starship Tech- nologies is making delivery robots. These are small, six-wheel things which drive on a side- walk amongst the people, and they can cover the last mile for delivery, be it pizza or per- sonal parcels, or something like that. And it's fully autonomous, so it finds its own way. Now they are cooperating with German automotive industries so that they can have a small mini- van to serve as a base for these guys. The mini- van stops in the middle of a city block, and then these small robots swarm out and deliver parcels. Then they go to next block. They call themselves a logistics company. I call them an electronics company because they have com- plex electronics and processing inside. Shaughnessy: If it can drive down the sidewalk among crowds of people, it must have sonar. Kolk: It has sonar and a bunch of cameras and lot of real-time processing. Shaughnessy: That's fascinating. It sounds like a good time to be in electronics in Estonia. Kolk: Absolutely. Shaughnessy: Thanks for your time, Arno. Kolk: Thank you for the opportunity, Andy. DESIGN007 In a step toward better diagnosis and treatment of digestive conditions, such as inflammatory bowel dis- ease, scientists report in ACS Biomaterials & Engineering that they have developed a first-of-its-kind collagen- based membrane for use in microchips. R e c e n t l y, re s e a rc h e rs developed a way to grow liv- ing cells in microfluidic chips. Commonly called a n organ- on-a-chip, each device is typically composed of a pair of flexible, translucent poly - mers or plastics that sur- round a porous membrane. The researchers produced three types of microfluidic devices. One had no membrane, and the second had a plas- tic-derived membrane. For the third device, the research t eam used collagen to form the membrane. Then, they placed human colon cells in each device. The research - ers concluded t h a t u s i n g c o l l a g e n - b ased mem- branes in organ-on-a-chip de vices enhance the growth, viability and barrier function of human colon cells and that the method likely could be extended to cells from other organs.
