Conference Paper
Copper Indium Gallium Selenide (CIGS) thin-film solar cells are a promising technology, but inline quality inspection systems are required for efficient high-volume production. Tests with two candidate methods: Raman spectroscopy and photo-luminescence imaging, are reported in this paper. The methods were used to estimate material compositions of C...
Chapter
Printing technologies are a convenient enabler for the rapid and cost-efficient prototyping as well as for the manufacturing of flexible sensors, which can be integrated in different types of materials and wearables. At the same time printing is considered to have a low environmental impact, provided that sustainable materials are used. As part of...
Conference Paper
The sensitivity of three different screen-printed highly stretchable liquid metal (Galinstan) sensors towards temperature and humidity as well as their electrical behavior under compressive load were studied. The sensors’ resistances show quasi linear dependence on changes in temperature without any hysteresis. Depending on the individual sensor de...

Fan-out wafer-level packaging (FOWLP) is an interesting platform for Microelectromechanical systems (MEMS) sensor packaging. Employing FOWLP for MEMS sensor packaging has some unique challenges, while some originate merely from the fabrication of redistribution layers (RDL). For instance, it is crucial to protect the delicate structures and fragile...
