Potential Applications:
- Biomedical research for analyzing cell concentrations and flow in microfluidic systems.
- Environmental monitoring for detecting pollutants in water or air.
- Industrial processes for quality control of liquids and gases.
Problems Solved:
- Accurate measurement of particle concentrations and flow in microfluidic channels.
- Precise detection of dielectric constant changes in different fluids.
- Improved monitoring and control of processes involving liquids and gases.
Benefits:
- Enhanced accuracy and sensitivity in measuring particle concentrations and flow.
- Real-time monitoring of dielectric constant changes for various fluids.
- Increased efficiency and reliability in analyzing microfluidic systems.
Original Abstract Submitted
a capacitive probe structure is presented including two or more microfluidic channels defined within a plurality of dielectric layers disposed over a substrate, and a plurality of probes extending through the plurality of dielectric layers such that several probes of the plurality of probes extend to the two or more microfluidic channels to measure at least particle concentrations and particle flow within the two or more microfluidic channels. the plurality of probes are physically and electrically isolated from each other by the plurality of dielectric layers. the plurality of probes further measure a dielectric constant change for conducting and non-conducting liquids and gasses within the two or more microfluidic channels.
