A system for the integrated/functional detection of different measurements is described. The system comprises a part wearable by a driver of a vehicle and plurality of sensors integrated in the wearable part and configured to supply the following driver parameters: breathing parameters, heart parameters, perspiration parameters and of the pressure exerted on the vehicle driving wheel. The system also includes a processor for processing the driver parameters and correlating them to a driver psychophysical condition.

A health monitoring garment is provided. The health monitoring garment includes an article of clothing comprising at least one compression section to provide a snug fit against a person wearing the article of clothing and a sensor island. The sensor island includes stretchable circuitry, two or more sensors, one or more power supplies, and optionally one or more wireless communication modules within a self-contained unit. At least one of the sensors comprises a stretchable sensor which may be a respiration sensor. The sensor unit may be provided independent of the health monitoring garment or as a complete system. The sensor island and compression section of the article of clothing also include fasteners of complementary geometries for reversible attachment and disengagement of the sensor island from the compression section.

Systems and methods are disclosed that provide smart alerts to users, e.g., alerts to users about diabetic states that are only provided when it makes sense to do so, e.g., when the system can predict or estimate that the user is not already cognitively aware of their current condition, e.g., particularly where the current condition is a diabetic state warranting attention. In this way, the alert or alarm is personalized and made particularly effective for that user. Such systems and methods still alert the user when action is necessary, e.g., a bolus or temporary basal rate change, or provide a response to a missed bolus or a need for correction, but do not alert when action is unnecessary, e.g., if the user is already estimated or predicted to be cognitively aware of the diabetic state warranting attention, or if corrective action was already taken.

Systems and methods for processing sensor data and self-calibration are provided. In some embodiments, systems and methods are provided which are capable of calibrating a continuous analyte sensor based on an initial sensitivity, and then continuously performing self-calibration without using, or with reduced use of, reference measurements. In certain embodiments, a sensitivity of the analyte sensor is determined by applying an estimative algorithm that is a function of certain parameters. Also described herein are systems and methods for determining a property of an analyte sensor using a stimulus signal. The sensor property can be used to compensate sensor data for sensitivity drift, or determine another property associated with the sensor, such as temperature, sensor membrane damage, moisture ingress in sensor electronics, and scaling factors.

A wearable sensor includes: a base member which is worn on a body of a wearer; a hole-like flow passage which penetrates through the base member; a sensor part which detects a signal as to electrical characteristics of a solution inside the flow passage; and a heater which is located in the base member in such a way as to enclose the flow passage.

A skin patch for use on a skin portion of a subject. The skin patch includes an analyte detector that detects an analyte from perspiration. The skin patch is adapted to release a marking agent such as a dye to mark the skin portion upon detection of the analyte.

Electronic eyewear configured to provide health condition or health risk monitoring or guidance to its user. Electronic eyewear, when being worn, is conveniently positioned to provide health condition or health risk monitoring. The eyewear can include various detectors for monitoring health conditions. The eyewear can also monitor the geographic location of the eyewear, which can impact risk level to the user. The eyewear can also measure distance to other persons for risk monitoring and/or facilitating contact tracing. The eyewear can serve to alert its user or facilitate alerting others. The user of the eyewear can configure a risk profile so that the eyewear provides customized health condition or health risk monitoring. Other embodiments can assist a user who is ill, such as, for example, by monitoring their health, monitoring for particular illnesses, tracking worsening conditions, and/or providing guidance to the user.

A perspiration sensing system includes a sensor patch and a smart device. The sensor patch includes one or more perspiration sensing portions. The one or more perspiration sensing portions include an inlet having a predefined size to receive perspiration from a predefined number of sweat glands and an outlet for reducing back pressure. At least one perspiration sensing portion includes a channel having a colorimetric sensing material that changes color when exposed to perspiration. At least one perspiration sensing portion includes a colorimetric assay in a substrate that changes color when exposed to biochemical components of perspiration. The system further includes a smart device having a camera that can take a picture of the sensor patch and determine the volume, rate of perspiration, and/or biochemical components of the perspiration from the one or more perspiration sensing portions.

A sweat sampling and sensing device for sensing sweat on skin includes an analyte-specific sensor for sensing a first analyte in sweat; a sweat collector placed on or adjacent to skin with a plurality of pores or pathways for entry of sweat from skin into said sweat collector, said sweat collector at least partly defining a sweat volume between said analyte-specific sensor and the skin; and a pressure element capable of holding said sweat collector against the skin with a pressure and reducing the sweat volume between said sweat collector and the skin.

Methods, structures, devices and systems are disclosed for fabricating and implementing electrochemical biosensors and chemical sensors. In one aspect, a method of producing an epidermal biosensor includes forming an electrode pattern onto a coated surface of a paper-based substrate to form an electrochemical sensor, the electrode pattern including an electrically conductive material and an electrically insulative material configured in a particular design layout, and attaching an adhesive sheet on a surface of the electrochemical sensor having the electrode pattern, the adhesive sheet capable of adhering to skin or a wearable item, in which the electrochemical sensor, when attached to the skin or the wearable item, is operable to detect chemical analytes within an external environment.
