Abstract :
This paper presents a near-infrared (NIR) electro-optical fluidic device with pulse width modulation (PWM) for flow injection glucose analysis. The device contains two emitter light emitting-diodes (LEDs), two photodiodes, and a poly (methyl methacrylate (PMMA) micro-fluidic. The pulsed LEDs have wavelengths of 1450 nm and 1650 nm (in the NIR spectrum range). Five concentrations of glucose solution can be detected by the proposed device. The LED was pulsed of different PWM and pulse frequency affect the amount of light received light voltage response for glucose detection. The optical fluid device is a cost-effective, simple structure without fibers and lenses for various glucose detection applications.
