Prototyping a photoacoustic glucose sensor using MEMS technology

人们正在寻求许多技术来开发新型的血糖传感器，包括非侵入性的、连续的监测器。然而，目前生产的设备中没有一种符合理想传感器的标准。这项研究探讨了利用硅微机械加工技术实现光声葡萄糖传感器小型化的可能性。利用样机传感器测量葡萄糖溶液浓度。光声信号与葡萄糖溶液浓度在0~1000 mg/d范围内呈线性关系。

Many technologies are being pursued to develop novel glucose sensors, including non-invasive, continuous monitors. However, none of the devices in production at present meet the criteria for the ideal sensor. This investigation examined the possibility of miniaturization of photoacoustic glucose sensors using silicon micromachining technology. A prototype sensor was used to measure glucose solution concentration. The photoacoustic signal was linearly proportional to the glucose solution concentration in the rage of 0 to 1000mg/d.
