Abstract
Apparatus, systems and methods of analyzing an in vitro flowing fluid using an in vitro sensor that operates using non-optical frequencies such as in the radio or microwave frequency bands of the electromagnetic spectrum. The in vitro sensor directs one or more signals that are in the radio or microwave frequency bands of the electromagnetic spectrum into an in vitro flowing fluid and detects one or more responses that result from transmission of the signal(s) into the in vitro flowing fluid.
Claims20
An in vitro sensing system, comprising:
- an in vitro sensor that is positioned adjacent to an in vitro fluid passageway that contains an in vitro flowing fluid;
- and
- the in vitro sensor includes:
- at least one transmit antenna and at least one receive antenna, the at least one transmit antenna is positioned and arranged to transmit a signal into the in vitro flowing fluid in the in vitro fluid passageway, wherein the signal is in a radio or microwave frequency range of the electromagnetic spectrum, and the at least one receive antenna is positioned and arranged to detect a response resulting from transmission of the signal by the at least one transmit antenna into the in vitro flowing fluid,
- wherein the at least one transmit antenna consists of a strip of conductive material having at least one lateral dimension thereof greater than a thickness dimension thereof, the strip of conductive material of the at least one transmit antenna is disposed on a substrate,
- the at least one receive antenna consists of a strip of conductive material having at least one lateral dimension thereof greater than a thickness dimension thereof, the strip of conductive material of the at least one receive antenna is disposed on the substrate,
- the at least one transmit antenna and the at least one receive antenna are coplanar with one another, and
- a geometry of the at least one transmit antenna differs from a geometry of the at least one receive antenna.
