Abstract: Fluid classification may include: receiving sensed data for the fluid; modeling the sensed data in a frequency domain; synthesizing a model of the sensed data from the frequency domain to a time domain response and converting the time domain response to a time frequency graphical representation in the form of a color map. Predetermined characteristics of the time frequency graphical representation are identified through computer vision and compared to at least one corresponding signature characteristic of a predetermined fluid type to identify the fluid as a fluid type.

Abstract: A surface enhanced luminescence (SELS) sensor may include a substrate and nano fingers projecting from the substrate. Each of the nano fingers may include a polymer pillar having a sidewall and a top, a coating layer covering the sidewall and a metal cap supported by and in contact with the top of the pillar.

Abstract: A microfluidic pressure sensor may include a reference chamber, a sensed volume, a microfluidic channel connecting an interior of the reference chamber to an interior of the sensed volume, a volume of liquid contained and movable within the microfluidic channel while occluding the microfluidic channel and a sensor to output signals indicating positioning of the volume of liquid along the microfluidic channel. Positioning of the volume of liquid along microfluidic channel indicates a pressure of the sensed volume.

Abstract: A luminescence-enhancement system can include a luminescence-enhancement sensor having a substrate and a group of nanofingers with individual nanofingers that can be flexible and include a support end attached to the substrate, a distal tip positioned distally with respect to the substrate, and a middle portion between the support end and the distal tip. A coating of a metal or metal alloy can be applied to the substrate and the distal tip that is conductively continuous. The middle portion can be devoid of the coating or the coating at the middle portion is conductively discontinuous. A liquid ejector can be present and can include a jetting nozzle to eject a liquid droplet having a volume of 2 pL to 10 μL. The group of nanofingers and the jetting nozzle can be positionable relative to one another for the droplet to be deposited on the group of nanofingers.

Abstract: In an example implementation, a substance detection device includes a chamber with chamber walls, a chamber top, and a chamber bottom. A substrate comprises imprinted nanostructures positioned within the chamber, and the substrate is coupled to the chamber walls to form the chamber bottom. An inert gas is sealed within the chamber.
