Prototyping a photoacoustic glucose sensor using MEMS technology

许多技术正在被用于开发新型的葡萄糖传感器，包括无创、连续监测。然而，目前生产中的设备都不符合理想传感器的标准。本研究探讨了利用硅微加工技术实现光声葡萄糖传感器小型化的可能性。一个原型传感器被用来测量葡萄糖溶液浓度。在0 ~ 1000mg/d范围内，光声信号与葡萄糖溶液浓度成线性关系。

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.
