Optical sensor platforms by modular assembly of organic electronic devices

Organic electronic devices are ideal for incorporation in sensor devices due to their reduced thickness, weight, and flexibility. Here, we show that organic light emitting diodes (OLED) and organic photodiodes (OPD) can be used in a wide range of optical sensors. Printing technologies allow for cheap production of devices. Using a modular build...

In Vitro demonstration of an SpO2-Camera

Feasibility of pulse oxigraphy is examined using an in- vitro phantom, perfused with human blood by a heart- lung machine. 29 different oxygen saturation levels, measured with our experimental camera and a clinical pulse oximeter, were matched against laboratory blood gas analysis. Discrete transfer functions between measurements & laboratory...

Contactless multiple wavelength photoplethysmographic imaging: A first step toward "spO2 camera" technology

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...
