Area of Science:

• Biomedical Engineering
• Electromagnetic Sensing
• Analytical Chemistry

Background:

• Rising healthcare costs necessitate economical, accurate, non-invasive continuous monitoring of blood analytes.
• Remote physiologic monitoring and care delivery are rapidly increasing.
• Existing methods for analyte measurement can be invasive or costly.

Purpose of the Study:

• To introduce and evaluate a novel electromagnetic technology, the Bio-RFID sensor, for non-invasive analyte measurement.
• To test the hypothesis that the Bio-RFID sensor can precisely measure and identify various analyte concentrations in vitro.
• To demonstrate the feasibility of using Bio-RFID for continuous, non-invasive monitoring applications.

Main Methods:

• Development of a novel Bio-RFID sensor based on radio frequency identification (RFID) technology.
• Proof-of-principle studies using deionized water with varying concentrations of isopropyl alcohol, salt, and commercial bleach.
• Randomized double-blind trial design to assess accuracy and precision.
• Analysis of radio frequency data converted into physiologically meaningful insights.

Main Results:

• The Bio-RFID sensor successfully detected analyte concentrations down to 2000 parts per million (ppm).
• Evidence suggests the sensor's capability to detect even smaller concentration differences.
• The technology demonstrated non-invasive measurement and identification of analytes in various solutions.

Conclusions:
