(author)Reflectance oximeters based on organic photodiode (OPD) arrays offer the potential to map blood pulsation and oxygenation via photoplethysmography (PPG) over a large area and beyond the traditional sensing locations. Here, an organic reflectance PPG array based on 16 × 16 OPD pixels is developed. The individual pixels exhibit near-infrared...article 2020

(author), Meulendijks, N.M.M. (author), Jansen, H. (author), Schoo, H.F.M. (author)Sensors based on organic electronic devices are emerging in a wide range of application areas. Here we present a sensor platform using organic light emitting diodes (OLED) and organic photodiodes (OPD) as active components. By means of lamination and interconnection technology the functional foils with OLED and OPD arrays form an in-plane...conference paper 2008

Wieringa, F.P. (author), Mastik, F. (author), van der Steen, A.F.W. (author), TNO Kwaliteit van Leven (author)We describe a route toward contactless imaging of arterial oxygen saturation (SpO2) distribution within tissue, based upon detection of a two-dimensional matrix of spatially resolved optical plethysmographic signals at different wavelengths. As a first step toward SpO 2-imaging we built a monochrome CMOS-camera with apochromatic lens and 3λ-LED...article 2005
