Abstract: According to a present invention embodiment, at least one sensor detects one or more gases emanating from one or more pathogens in a wound that produce an infection. The at least one sensor includes sensing materials that change one or more properties in response to a presence of the one or more gases. At least one processor analyzes information from the at least one sensor to identify the one or more pathogens and determine a presence of the infection in the wound. The one or more pathogens are identified based on patterns of changes of the one or more properties indicating corresponding pathogens. The at least one sensor may be disposed within one of a wearable device, a portable device, and a wound dressing. In addition, a negative pressure source may be utilized to apply negative pressure to the wound to promote healing.

Abstract: A device for monitoring one or more health conditions of a subject in need thereof has a plurality of sensor arrays adapted to detect, from a skin surface of the subject, a plurality of volatile organic compounds (VOCs), one or more vital signs, or both, and to generate electrical signals; one or more processors for processing the electrical signals from the plurality of sensors, generating data, and diagnosing one or more health conditions of the subject by correlating the generated data with the one or more health conditions; an interface for outputting data and/or receiving input commands; and a fixing member for placing the device to the skin surface of the subject.

Abstract: A method of detecting acetone in a gas sample, comprising, at an operation temperature of 50° C. or less, exposing the gas sample to a gas sensor comprising an electrode and a sensing material deposited on the electrode, wherein the sensing material comprises tungsten bronze, and a level of the acetone in the gas sample is detected by a change in resistivity of the sensing material.

Abstract: A multi-channel direct-deposit assembly method is disclosed to high-throughput synthesize three-dimensional macroporous/mesoporous (3DMM) material array with precisely controlled composition, pore size, and pore structure. The macropore size of the synthesized 3DMM material is in the range of 50-1000 nm; the mesopore size of the synthesized 3DMM material is in the range of 1-50 nm. The surface area of the 3DMM material is in the range of 20-1000 m2/g. The 3DMM material array can be used for rapid synthesis, screening and manufacture of catalysts and nanosensors.
