Measuring Pressure: Introducing oBPM, the Optical Revolution for Blood Pressure Monitoring
(2018-09)According to the World Health Organization, every third adult suffers from hypertension-which amounts to 1 billion adults worldwide. Hypertension can lead to severe complications, such as stroke and heart failure. Each ... -
Mechanically stacked 4-terminal III-V/Si tandem solar cells
(2017)We developed 4-terminal III-V/Si dual-junction solar cells that reach certified record 1-sun efficiencies over 32%. These efficiency values exceed the theoretical efficiency limit of single-junction solar cells and prove ... -

MEMS scanner with 2D tilt, piston and focus motion
(2017)A MEMS scanner with a high level of motion freedom has been developed. It includes a 2D mechanical tilting capability of and/-15 degrees, a piston motion of 50 mu m and a focus/defocus control system of a 2mm diameter ... -
MEMS Tunable Littman-Metcalf Diode Laser at 2.2μm for Rapid Broadband Spectroscopy in Aqueous Solutions
(2018)We demonstrate a rapidly (3 ms) and widely (222 nm) tunable, compact external cavity GaSb-based diode laser with a MEMS mirror. It delivers from 8 to 24 mW power over the tuning range, showing the side-mode suppression ... -
Metallization of Si heterojunction solar cells by nanosecond laser ablation and Ni-Cu plating
(2017)A key step in industrialization of photovoltaics (PV) is the development of low-cost and large-area metallization processes to substitute the standard screen-printing process of silver paste. Thus Cu and Ni metallization ... -
Method-comparison study between a watch-like sensor and a cuff-based device for 24-h ambulatory blood pressure monitoring
(2023-04-15)Abstract The use of 24-h ambulatory blood pressure monitoring (ABPM) has been continuously increasing over the last decades. However, cuff-based devices may cause discomfort, particularly at night, leading to ... -
Microcrack characterization in loaded CFRP laminates using quantitative two- and three-dimensional X-ray dark-field imaging
(2018)In this work we present a method to characterize microcracks in carbon fiber reinforced polymer (CFRP) samples with a diameter up to 120 mm using quantitative grating-based X-ray dark-field imaging. In contrast to conventional ...
