egm1000™ gives you freedom from finger-pricking to help you manage your diabetes.
egm1000™ is battery-operated and includes a Main Unit (MU), which contains display and control features, as well as transmitter, receiver and processor, and an Ear Clip (EC), which is clipped to the earlobe and contains sensors and calibration electronics.
The device is small, light and easy to use. The Main Unit can be shared by up to three users, although each user requires his/her own (individually calibrated) EC. The device includes a USB port for data downloading (enables off-line analysis), as well as battery recharging.
Measures your tissue glucose (sugar level /diabetes) in three ways
Each method measures one skin tissue parameter.
Three independent readings are combined to give a reading with above 95 % accuracy.
An ultrasonic wave travels from a transmitter, placed on one side of the earlobe, through the earlobe tissue and received at the other side. The sound velocity depends linearly on the glucose concentration.
The EGM1000 ear-clip utilizes a dielectric material between the two capacitor plates. Small electric voltage application between the two plates stimulates the earlobe tissue, allowing for impedance assessment. Impedance is the effective resistance of an electric circuit to alternating current. The tissue impedance depends on the glucose concentration.
A small amount of controlled energy is applied to the earlobe using a heat source. The temperature developed on the earlobe as a result of the heating depends on the level of glucose.
Measures your diabetes in three ways
Each technology measures different tissue parameters that are affected by the same change in glucose concentration, but is confined by the impact of interfering factors, due to lack of specificity. Therefore, a simultaneous evaluation of the above mentioned physiological changes through measurement of different sets of tissue perturbations, induced by changes in glucose concentration, increases the validity of the end result. The three independent readings are combined together by a proprietary algorithm, which calculates their weighted average.
(phase shift as a function of speed of sound change within the tissue) – An ultrasonic wave travels from a transmitter, placed on one side of the earlobe, through the earlobe tissue and received at the other side. Zips et al  showed that the sound velocity depends linearly on the glucose concentration in a water-glucose solution. They also described sound velocity dependency on temperature. Moreover, the temperature dependence is more significant than that of the glucose concentration. One should note that these dependencies are not opposite to each other, meaning in the hyperglycemic range, the temperature increases as well as the concentration and thus the velocity of sound is expected to increase significantly. Furthermore, in live tissues, the influence of glucose concentration on the velocity of sound is more profound than the demonstration in Zips and associates’ study. This is since glucose-induced water transport affects tissue density as well as compressibility and they also affect the sound velocity .
(conductivity of the tissue) – The device has two parallel foils, which act like capacitor’s plates. Thus the earlobe utilizes as a dielectric material between the two capacitor plates. Voltage application between the two plates stimulates the earlobe tissue, current measurement allows for impedance assessment. This method is plausible as a glucose assessment technique since plasma glucose induces ion shift across the cellular membrane in red blood cells and as a result changes membrane potential . Furthermore, Hayashi et al  demonstrated that variations of the metabolically active enantiomer d-glucose affect the permittivity and conductivity of the cellular membranes. Tissue impedance is changed due to changes in blood glucose concentration and is therefore monitored .
(heat capacity of the tissue) – A known (controlled) amount of energy is applied to the earlobe using a heat source for a predetermined period of time. The temperature developed on the earlobe as a result of the heating is glucose dependent, according to the bio-heat transfer equation, which describes the thermal properties changes of a living tissue .
