Abstract

A micrometer size, simple, and low-cost sensor for continuous monitoring of human blood during malarial infection at its various stages is proposed in this work. The sensor comprises a light source, silica fiber directional coupler, and an optoelectronic photodetector. The sensor is simulated for fiber diameters from 1–1.8 #x03BC;m and optimization is done. The sensor produces a photocurrent of a few mA, which gives the level of infection. It can detect a change in refractive index, of the order of 10−5, and needs a small sensing length of a few μm. It can be potentially built as an integrated embedded device.

利用微型光纤耦合器传感器装置监测疟疾的不同阶段

提出了一种微米大小、简单、低成本的传感器，用于在疟疾感染的各个阶段连续监测人类血液。该传感器包括光源、二氧化硅光纤定向耦合器和光电光电探测器。对光纤直径1 ~ 1.8 #x03BC;m范围内的传感器进行了仿真，并进行了优化。传感器产生几毫安的光电流，这就给出了感染的程度。它可以检测到10−5量级的折射率变化，并且传感长度很短，只有几μm。它可以作为一个集成的嵌入式设备。
