Abstract
A DS sensing apparatus includes a body and electrodes provided on the body. The body defines a test volume between a first surface and an opposing second surface spaced from the first surface a distance that allows a fluid to enter the test volume from a fluid inlet, which is communicatively coupled to the test volume, via capillary action. The electrodes include a first sensing electrode on the first surface and configured to receive an input RF signal, a second sensing electrode on the first surface spaced from the first sensing electrode and configured to deliver an output RF signal and a floating electrode on the second surface.
Claims13
A method of assembling a DS (dielectric spectroscopy) sensing apparatus, the method comprising:
- disposing a circuit support into a cavity formed in a lower body;
- affixing a first insert to the lower body, wherein the first insert includes at least one of a first terminal end of a first sensing electrode and a first terminal end of a second sensing electrode, wherein affixing the first insert includes disposing the first insert in the cavity formed in the lower body, and over the circuit support such that the circuit support is separated from a test volume by the first insert;
- affixing a second insert to an upper body, wherein the second insert includes a floating electrode deposited thereon;
- and
- connecting the lower body and the upper body to form a body.
A method of assembling a DS (dielectric spectroscopy) sensing apparatus, the method comprising:
- affixing a first insert to a lower body, wherein the first insert includes at least one of a first terminal end of a first sensing electrode and a first terminal end of a second sensing electrode;
- affixing a second insert to an upper body, wherein the second insert includes a floating electrode deposited thereon;
- disposing a circuit support between the upper body and the lower body such that at least one assembly aperture defined in the circuit support receives at least one assembly pin extending from one of the upper body and the lower body;
- and
- connecting the lower body and the upper body to form a body.
A method of assembling a DS (dielectric spectroscopy) sensing apparatus, the method comprising:
- affixing a first insert to a lower body, wherein the first insert includes at least one of a first terminal end of a first sensing electrode and a first terminal end of a second sensing electrode;
