Device And Method For Detecting Miniature Targets In A Fluid Sample - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240036000 titled 'Device And Method For Detecting Miniature Targets In A Fluid Sample

Simplified Explanation

The abstract describes a patent application for a substrate with a sensing transistor and voltage reference transistors on one side, and a structure with openings for collecting fluid on the opposite side. The sensing transistor detects the presence of miniature targets in the fluid through capacitive coupling with a sensing film.

  • The substrate has a sensing transistor and voltage reference transistors on one side.
  • The structure on the opposite side of the substrate has openings for collecting fluid.
  • The sensing transistor detects the presence of miniature targets in the fluid through capacitive coupling.
  • The voltage reference transistors are located on different lateral sides of the sensing transistor.
  • The sensing film is placed over the substrate to detect the presence of targets in the openings aligned with the sensing transistor.

Potential Applications:

  • Medical diagnostics: The technology can be used for detecting specific biomarkers or pathogens in bodily fluids.
  • Environmental monitoring: It can be applied to detect pollutants or contaminants in water or air samples.
  • Industrial quality control: The system can be used to identify impurities or defects in manufacturing processes.

Problems Solved:

  • Improved sensing capabilities: The capacitive coupling allows for sensitive detection of miniature targets in the fluid.
  • Versatile design: The placement of voltage reference transistors on different sides enhances the accuracy and reliability of the sensing system.
  • Easy fluid collection: The structure with openings simplifies the process of collecting fluid samples for analysis.

Benefits:

  • High sensitivity: The capacitive coupling enables the detection of even small targets in the fluid.
  • Accurate and reliable: The placement of voltage reference transistors improves the precision and consistency of the sensing system.
  • Easy to use: The structure with openings makes it convenient to collect fluid samples for analysis.
