Partners’ testimonials
Prof. Norbert Fruehauf
Director of IGM at University of Stuttgart
The XTPL’s ability to directly deposit (in a mask-less approach) electrically conductive structures in the minimum feature size range of 1.5 – 10 micrometers is unique. In my view the XTPL’s ultra-precise deposition technology offers truly unique properties, which are an excellent fit to the future needs in the field of printable high-resolution and foldable OLED displays.
Prof. Ravinder Dahiya
The Leader of the BEST research group at the University of Glasgow
Our research revolves around the development of high-performance printed electronics and sensing systems on large area flexible substrates. We used these printed systems to develop flexible electronic skin (eSkin) and explore its application in healthcare, wearable systems and robotics. In our projects we also use micro/nanofabrication tools and align them with processing on flexible substrates. We decided to purchase the Delta Printing System for our labs, after performing initial tests with the team at XTPL over the last several months. This appears to be a great enabling tools and we are looking forward to including it in our daily research work.
Do Soon Jung
Vice President at HB Technology
Our relationship with the XTPL team has successfully continued for 24 months now. In that time, we have deeply evaluated different printing technologies available worldwide for some of the most challenging use-cases in ultra-high resolution next generation displays. In our collaboration, the XTPL team demonstrated that their technology has a unique technological solution and a very good potential to enable manufacturing of the next generation flat panel displays. Putting the XTPL device to use for validation of the XTPL technology at the R&D level will help us to strengthen the collaboration and accelerate the joint introduction of XTPL technological solutions to our end customers, who are the leading global manufacturers of FPDs. We are looking forward to growing our relationship and collaboration with the XTPL team for the future.
Prof. dr Emil List-Kratochvil
Head of the Hybrid Devices group and expert in organic semiconductors and printed semiconductor devices., Humboldt University of Berlin
We became very much interested in the UPD method developed by the XTPL team. We first learned about it and the Delta Printing System at the ISFOE conference series in 2021. After we had the opportunity to find out about the capabilities of the method, we decided that the device would be a great tool for our scientists who are working on new technologies for sensor, photovoltaic and optoelectronic solutions. We are not going to stop at the academic research phase: moving forward, we’re planning to implement the results in real-life applications at our industrial partners who have been cooperating with our institute for a long time.
Prof. Fabrizio Torricelli
University of Brescia
One of the focus areas for our research is the development of assistive technologies for the production of a modern class of biosensors, which are sought after by global industrial clients and which must satisfy their current requirements, including in terms of environmental protection. Another aspect is the ability to micro -fabricate – or build micrometric devices and components. Microfabrication of bioelectronic devices for detecting a single molecule requires the capability of applying ultra-thin conductive structures with a width and pitch below 1 micrometer, as well as with an appropriate viscosity index. Until now, our University did not have a proper system for this purpose – no such solution was available on a global scale.
