Abstract

This study describes the functioning of a novel sensor that measures the alcohol concentration in the interstitial fluid (ISF) of a human subject. ISF is extracted using vacuum pressure from micropores on the stratum corneum layer of the skin. The pores are created by focusing a near infrared laser on a layer of black die attached to the skin. This poration procedure is essentially painless. Clinical studies show that the sensor readings are correlated with alcohol levels in blood and collected using a breathalyzer. Alcohol could be detected in the subject's ISF within 15 min of the first oral intake of alcohol. Tests in a laboratory setup show that the sensor exhibits a linear response to alcohol concentrations in the range 0%-0.2%. The sensor is minimally invasive and alcohol monitoring using the sensor was shown to continue even when the subject is asleep. The sensor is viable for approximately three days after skin poration. The sensor is interfaced to a wireless health monitoring system that transfers sensor data over existing wide-area networks such as the Internet and a cellular phone network to enable real-time remote monitoring of subjects.

  • ISF composition leads to reliable correlations between blood and ISF concentrations of many analytes, including electrolytes, metabolites, and proteins.

    “This function, and the associated ISF composition, lead to reliable correlations between the blood and ISF concentrations of many analytes, including electrolytes (e.g., sodium, phosphate, magnesium, potassium or calcium), metabolites (e.g., glucose, alcohol, lactate or cortisol) and proteins65-69.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
