Outcome Measures
Primary Outcomes (4)
Phase shift of scattering parameter S21
The proposed microwave sensor uses a section of planar metamaterial transmission line operating at GHz frequencies. The speed of electromagnetic wave propagation through the sample is affected by the concentration of glucose. The delay can be expressed in degrees (°) as the phase of the complex S21 parameter.
When blood sample is filled into sensor chamber within 24 hours from blood collection.
Blood glucose concentration
Molar mass of glucose dissolved in liquid blood sample expressed as molar concentration (mmol/l).
When blood sample is processed in biochemical analyzer within 24 hours from blood collection.
Blood sample specific electrical conductivity
The specific electrical conductivity (S/m) of the blood samples will be measured using a coaxial probe.
When blood sample is presented into the co-axial probe container within 24 hours from blood collection.
Blood sample relative permittivity
The relative permittivity (-) of the blood samples will be measured using a coaxial probe.
When blood sample is presented into the co-axial probe container within 24 hours from blood collection.
Secondary Outcomes (2)
Sensor sensitivity
After primary data acqiusition.
Mathematical model of blood glucose dependence on blood dielectric parameters
After primary data acqiusition.
Study Arms (1)
Blood sample donator
EXPERIMENTALThe participant donates approximately 5 ml of blood sample.
Interventions
Participant will donate approximately 5 ml blood sample. Later in a laboratory the sample will be processed in the microwave metamaterial sensor for non invasive blood glucose monitoring and standard biochemical analyzer. Specific dielectric properties and scattering parameters will be measured for blood glucose level determination.
Eligibility Criteria
