| Abstract |
A blood-glucose meter is an in vitro diagnostic device to measure and control glucose in the blood of the diabetics. Although ICT technology has been advanced, the blood-glucose measurement system still consists of a lancet, a strip, and a meter and it is difficult to share the measured data to others such as a doctor or family. This paper designs and implements an energy harvesting blood-glucose meter based on NFC to measure the glucose level in the blood. The proposed blood-glucose meter based on NFC does not contain its own battery, but it harvests energy from NFC frequency transmitted by the smartphone and then it operates the system. The blood-glucose meter based on NFC goes through some process including measurement, correction, and transmission needed for glucose measurement. In order to display the measured data to the user, to store it to the database, to send or receive to/from another device, this paper also implements a dedicated Android application. In addition, we also conducted performance evaluation to verify the superiority of the proposed blood-glucose meter. The result shows that standard deviation is approximately 17nA and the repeat measurement error in a single device is approximately within ±17.5nA which is much smaller than the requirement of ISO 15197. The proposed blood-glucose meter based on not only has the superiority than traditional meters in cost and convenience but also can provide smart functions such as remote diagnosis. |
