GoBe Smart Wristband: It is not the blood glucose value that is measured, but the liquid condition. The blood value is calculated by data calculation through this liquid change. The GoBe wristband captures changes in intracellular fluid through resistance sensors and collects high and low frequencies for blood glucose monitoring. Although the resistance sensor cannot directly measure sugar, it can measure liquid change, which depends on sugar absorption. If users consume low-sugar (sugar-free) food, the GoBe wristband will be converted by a "Flow Technology", which has the learning ability to achieve a more accurate after a few days or weeks. Monitoring results. Not certified. <br />Requires mobile phone, priced at 1,799 RMB.
