Methods and systems for monitoring workplace safety and evaluating risks is provided, the method comprising receiving signals from at least one wearable device, identifying portions of the signals corresponding to physical activities, excerpting the portions of the signals corresponding to the physical activities, and calculating risk metrics based on measurements extracted from the excerpted portions of the signals, the risk metric indicative of high risk lifting activities.

A device for determining the amount or concentration of an analyte in a fluid sample and a flow rate of the fluid sample in a channel is provided. The device includes a chamber including a channel and an opening the channel in fluid communication with the opening. The device further includes a wicking component positioned adjacent to the opening configured to receive an amount of fluid from the channel. The device may further include an analyte sensor positioned on the wicking component, the analyte sensor configured to detect an analyte in fluid in contact with the analyte sensor, wherein the wicking component is configured to contact the amount of fluid with the analyte sensor. Alternatively the device may include at least one pair of electrodes configured to determine a flow rate of the fluid in the channel.

The present disclosure discloses a novel omniphobic, paper-based, smart bandage (OPSB) devices, and the methods to make and use the omniphobic, paper-based, smart bandage devices. The OPSB device of the present disclosure provides a simple, low-cost, and non-invasive strategy to monitor open wound status wirelessly. This disclosure also provides the demonstration of in-vivo early detection and monitoring of pressure ulcers using wireless smart bandages.

A wearable paper-based platform with simultaneous passive and active feedback for monitoring perspiration is provided. The sensor platform comprises two modules: a disposable wicking-based sweat collection patch with discrete colorimetric feedback, and a reusable electronic detachable module for active feedback. The disposable patch comprises a hygroscopic wicking material laminated between two polymeric films. The wicking material is patterned with a radial finger design that offers discretized visual readout of the sensor. The active module attaches to the film and alerts the user when the film collects a pre-determined volume of sweat. The multi-feedback system allows high-performance athletes who value objective quantification of perspiration to better assess their sweat loss during physical activities.

A system 100, 200 for sensing one or more analytes in a first biofluid and a second biofluid and methods of using said system. The system 100, 200 may include a first subsystem 102, 200a, 200b with a first sensor 120, 122, 220, 222 for sensing a first analyte in the first biofluid and a second subsystem 104, 200b, 200c with a second sensor 124, 126, 222, 224 for sensing a second analyte in the second biofluid. The second analyte may be the same as or different from the first analyte and the second biofluid may be different from the first biofluid. In an embodiment, the first biofluid is a non-sweat biofluid and the second biofluid is sweat. The system 100, 200 may be used to detect lag time for measuring an analyte in one of the biofluids.

Techniques and systems are disclosed for implementing textile-based screen-printed amperometric or potentiometric sensors. The chemical sensor can include carbon based electrodes to detect at least one of NADH, hydrogen peroxide, potassium ferrocyanide, TNT or DNT, in liquid or vapor phase. In one application, underwater presence of chemicals such as heavy metals and explosives is detected using the textile-based sensors.

Described herein are devices for collecting and analyzing a fluid sample, the devices comprising a fluid-collecting porous material comprising at least one hydrophilic porous layer and one or more sensors adapted to provide a response to the presence of an analyte. The detectors are useful for collecting and analyzing a very small volume of sample and may include features that facilitate and direct flow of the sample through porous material.

Disclose is a dry adhesive patch comprising: a plurality of embossed pillars formed on a substrate; a hemi-spherical adsorbing cup defining a top portion of each pillar, wherein a hemi-spherical hole is defined in a top portion of the adsorbing cup and is exposed to an outside; and an annular extension extending radially from an outer perimeter of a distal end of each adsorbing cup.

Disclosed is a postprandial glucose-measuring device for preventing the development of or reversing T2D. Included are methods for using the device as well as better use for invasive and noninvasive glucose meters. Further disclosed are novel exercise-sensitizing compositions useful for managing blood glucose levels in Type-2 diabetics with minimal risk of hypoglycemia. The disclosed glucose meters allow a user to also measure exercise and meal sizeall with relatively instant feedbackmore effectively than having to track the complexity posed by labels, glycemic index and calories. Also disclosed is integration of glucose-measuring devices with smartphones and health monitoring technology to make possible safe and effective interpretation of postprandial glucose readings by a patient to control or reverse Type-2 diabetes.
