Abstract: The invention discloses a quasi-volumetric sensing system and method. Plural short-range order (SRO) units are configured on the carrier of a quasi-volumetric device, and arranged as an array, i.e. a long-range order (LRO) unit. Protrusions, configured on the SRO units, can modify the wettability of the carrier to control the liquid volume retained thereon so that the precise volume of the liquid sample or droplets are calculated. Based on the applied force on the LRO unit and the gradient of hydrophilicity-hydrophobicity on the surface, the redundant volume of the liquid sample is removed. Macromolecules, e.g. antibodies, complements, receptor proteins, aptamers, oligosaccharides or oligonucleotides, configured on the protrusions are coupled to specific molecules in the liquid sample or droplets so as to determine characteristics of the specific molecules. Therefore, the open chip device of the invention can be used to achieve the quasi-volumetric measurement and the analysis of specific molecules.

Abstract: A strip for an electronic device senses a liquid sample. The strip includes a substrate having a first surface, a plurality of protrusions disposed on the first surface, and each having a width, and a hydrophilic layer having a layer surface disposed on the first surface and the plurality of protrusions, and having a second surface opposite to the layer surface, whereby the liquid sample and the second surface have a contact angle therebetween ranging from 2 to 85 degrees when the liquid sample is disposed on the hydrophilic layer.

Abstract: A planar volumetric device for quantifying and handling a body fluid sample is provided. The device has a planar main body, a body fluid sample flow path, an air pump and an air passage. The planar main body includes a first planar surface and a second planar surface. The body fluid sample flow path is disposed in the main body, and has a body fluid sample inlet, a middle junction and a body fluid sample outlet, wherein the middle junction and the body fluid sample outlet define therebetween a specific path segment, by which it is possible to externally observe to which extent the body fluid sample has filled up with the path segment. The air pump is configured to provide an operating air pressure. The air passage has a first end and a second end, wherein the first and the second ends are connected to the air pump and the middle junction respectively, and the specific path segment has a constant volume.
