Apparatus, systems and methods for sensing an analyte such as ethanol
First Claim
1. An apparatus for sensing an analyte, comprising:
- a substrate having a first rigid region and a first trench region, the first trench region being thinner than the first rigid region; and
a sensor block supported by the first rigid region, the sensor block comprising;
a frame layer extending upwardly from the first rigid region, the frame layer having a first end opposite the substrate to engage with a tissue sample, the frame layer having an opening therein extending between the substrate and the first end defining a pocket; and
a sensor located within the pocket distal the first end, the sensor comprising;
a first substance having a property adapted to change in response to the presence of the analyte; and
a resonant element covered by the first substance and operable to detect the change in the property of the first substance;
wherein the first trench region is laterally positioned relative to the first rigid region and the sensor block to provide for flexed deformation of the substrate within the first trench region upon flexing the substrate.

Abstract
According to one aspect, a system for sensing ethanol from human skin, that comprises at least one apparatus for sensing ethanol and a coupling matrix readout extraction unit for performing a method of extracting a coupling-matrix readout. The at least one sensing apparatus and the coupling matrix readout extraction may be mounted on a substrate. The substrate may be adapted such that it can be formed into a wearable accessory that can be worn by a human subject. When the wearable accessory is worn by the human subject such that the subject provides a skin tissue sample to the accessory, the presence or concentration of ethanol and other compounds may be determined from the vapor associated with the tissue sample.
