In order to increase the accuracy of non-invasive glucose measurement, the device uses a combination of three non-invasive methods: ultrasonic, electromagnetic and thermal. The non-invasive glucose monitor comprises a Main Unit, which drives three different sensor channels (one per technology), located on an external unit configured as an ear clip attached to the subject’s ear lobe. To effect the ultrasonic channel, ultrasonic piezo elements are positioned on opposing portions of the ear clip and thus opposite sides of the ear lobe. For implementation of the electromagnetic channel, capacitor plates are positioned on opposing portions of the ear clip and the ear lobe serves as the dielectric. The thermal channel includes a heater and a sensor positioned on the ear clip in close juxtaposition to the ear lobe.為了增加無創血糖測量的精度，該設備使用三種無創方法的組合：超聲、電磁和熱。該無創血糖監測儀包括驅動三個不同感測器通道(每種技術一個)的主單元，上述感測器通道位於被配置為附連到受檢者的耳垂的耳夾的外部單元上。為了實現超聲通道，超聲壓電元件定位在耳夾的相對部分上並且因此定位在耳垂的相對側面上。為了實現電磁通道，電容器板定位在耳夾的相對部分上並且耳垂充當電介質。熱通道包括緊鄰耳垂定位在耳夾上的加熱器和感測器。
