A fluid level sensor is configured for identifying a fluid level in a small volume reservoir, such as a fluid reservoir in an ejector head. The reservoir includes a plurality of vertically arranged chambers. A plurality of piezoelectric transducers is distributed over the chambers in a one-to-one correspondence. At least one electrical conductor is electrically connected to each piezoelectric transducer in the plurality of piezoelectric transducers to enable each piezoelectric sensor to receive an electrical signal to a portion of a wall of the chamber to produce an acoustical wave in the chamber and to transmit an electrical signal from each piezoelectric transducer in response to a fluctuating pressure on each piezoelectric transducer produced by the acoustical wave in the chamber.

The present disclosure proposes a colorimetric method that couples sensor design with image processing to enable automated evaluation of test results obtained by paper-based sensors. The proposed method can match ink color and dye used in colorimetric reaction in terms of their absorption in spectral range (e.g., red, green, blue). A near-zero absorption channel can then be used to normalize absorption channels and construct a composite image.

A chemical assay device includes a hydrophilic substrate and one or more hydrophobic structures that extend from a first side of the hydrophilic substrate to a second side of the hydrophilic substrate. A hydrophobic structure in the hydrophilic substrate forms a fluid barrier wall that extends from the first side of the hydrophilic substrate to the second side of the hydrophilic substrate with a deviation of less than 20&#xb0; from a perpendicular axis between the first side and the second side. The hydrophobic structure is formed from a wax or a phase change ink.

A chemical assay device includes a hydrophilic substrate and one or more hydrophobic structures that extend from a first side of the hydrophilic substrate to a second side of the hydrophilic substrate. A hydrophobic structure in the hydrophilic substrate forms a fluid barrier wall that extends from the first side of the hydrophilic substrate to the second side of the hydrophilic substrate with a deviation of less than 20&#xb0; from a perpendicular axis between the first side and the second side. The hydrophobic material in the first hydrophobic structure occupies more than 50% of a void volume fraction of the hydrophilic substrate.

The present disclosure proposes a design of a biomedical paper sensor which can determine the concentration of biological materials in fluids such as blood, urine, and saliva. The sensor contains a plurality of axially radiating test zones, each test zone separated from other test zones by wax ink barriers formed by a process that produces thin walls. Each test zone can contain a unique test reagent, or a unique concentration of a test reagent, and can also be identified by printed text. The region of the device outside of the test zone area is printed with a uniform reference color. Benefits of the invention include increased accuracy in the measurement of the concentration of biological materials due to the larger test zone area. Benefits also include the integration of the reference or calibration color which simplifies the calibration needed for quantification of the concentration.
