Each innovation started once with a smart invention. This small seed can grow into a successful product, provided there are the right circumstances. One aspect is the protection of the intellectual property of the invention so that it can be defended against competitors. Therefore, I’m glad that there is an efficient process to obtain this protection.…

I have finally completed all 6 masterclasses from The Engineering EEcosystem. The masterclasses contain very valuable information. Eric Bogatin is great at explaining electrodynamics from a practical perspective without going into Maxwell’s equations. I really enjoyed his style of teaching. Now I even remember Eric’s famous rule #9 and that the answer to all questions…

I’m happy to share that the paper 🌐DOI:10.1038/s41598-025-06818-9 has just been published in Scientific Reports. It demonstrates how polycaprolactone (PCL) powder can be melted in a focused ultrasonic field in the presence of water. This also gives control over the porosity of the printed objects. As PCL is already used in biomedical applications, this new…

My paper got published today, and I’m really impressed with the bold upselling strategies of this particular publisher.

I’m so thankful, that the Jane and Aatos Erkko Foundation is supporting my research on acoustic 3D printing. Their grant gives me the opportunity to dive deeper into acoustic 3D printing and develop new applications.I’m further thankful for the support of the University of Helsinki where I can perform my research for the next years.…

You may be wondering what this construction is used for. When you work in the field of ultrasonics (in water), it is pretty common that you need to get rid of some air bubbles that adhere to some surfaces. This tool can flush them away with a jet of water. I have already built several…
